From 84fa83d079aa05cfb126339ba8104ac6797b9b9a Mon Sep 17 00:00:00 2001 From: Enrico Rubboli Date: Thu, 17 Sep 2026 22:59:51 +0400 Subject: [PATCH 01/36] refactor: extract type-agnostic transaction assembler Move everything not specific to a transaction type out of buildTransaction into a private assembleTransaction({outputs, inputs, requiredCoin, requiredToken, sendToken, baseFee, deductFeeFromFirstOutput, opts}). buildTransaction now only computes the required outputs/inputs and coin/token requirements via getRequiredInputsOutputs, adds the per-type fee via getFeeForType and delegates to assembleTransaction. The DelegationWithdraw special cases (no coin selection, fee deducted from the first output) are modeled by the deductFeeFromFirstOutput flag. Public APIs and behavior are unchanged. Reviewer note: subagent tooling is unavailable in this environment, so the correctness/TS, security and DRY reviews were run manually on the diff (clean, zero findings). One invariant change: getRequiredInputsOutputs (pure, synchronous) now runs before the UTXO fetch instead of after. --- packages/sdk/src/mintlayer-connect-sdk.ts | 107 +++++++++++++++------- 1 file changed, 76 insertions(+), 31 deletions(-) diff --git a/packages/sdk/src/mintlayer-connect-sdk.ts b/packages/sdk/src/mintlayer-connect-sdk.ts index 4903529..dd3d490 100644 --- a/packages/sdk/src/mintlayer-connect-sdk.ts +++ b/packages/sdk/src/mintlayer-connect-sdk.ts @@ -887,6 +887,18 @@ type TransactionOpts = { forceSpendUtxo?: UtxoEntry[]; }; +type AssembleTransactionArgs = { + outputs: Output[]; + inputs?: Input[]; + requiredCoin: bigint; + requiredToken: bigint; + sendToken?: { token_id: string; number_of_decimals: number }; + baseFee: bigint; + /** Take the fee from the first output instead of the coin inputs (DelegationWithdraw semantics). */ + deductFeeFromFirstOutput?: boolean; + opts?: TransactionOpts; +}; + type BuildTransactionParams = | { type: 'Transfer'; @@ -2442,31 +2454,37 @@ class Client { } /** - * Builds a transaction based on the provided parameters. - * @param{BuildTransactionParams} arg + * Assembles a transaction from caller-provided outputs and coin/token requirements. + * + * Fetches UTXOs (unless overridden via `opts.withUTXO`), selects inputs to cover + * `requiredCoin`/`requiredToken` (plus fee), runs the fee-iteration loop, appends + * change outputs, encodes the transaction and computes its id. + * @private */ - async buildTransaction(arg: BuildTransactionParams): Promise { - const { type, params } = arg; - - this.ensureInitialized(); - if (!params) throw new Error('Missing params'); - - console.log('[Mintlayer Connect SDK] Building transaction:', type, params); - + private async assembleTransaction({ + outputs, + inputs = [], + requiredCoin, + requiredToken, + sendToken, + baseFee, + deductFeeFromFirstOutput = false, + opts, + }: AssembleTransactionArgs): Promise { const address = this.connectedAddresses; const currentAddress = address; const addressList = [...currentAddress.receiving, ...currentAddress.change]; let data_utxos: UtxoEntry[]; - if (arg?.opts?.withUTXO) { - data_utxos = arg?.opts?.withUTXO; + if (opts?.withUTXO) { + data_utxos = opts.withUTXO; } else { data_utxos = await this.apiProvider.getAccountUtxos(addressList, this.network === 'mainnet' ? 0 : 1); } - const forceSpendUtxo: UtxoEntry[] = arg?.opts?.forceSpendUtxo - ? arg?.opts?.forceSpendUtxo.map((item: UtxoEntry) => ({ + const forceSpendUtxo: UtxoEntry[] = opts?.forceSpendUtxo + ? opts.forceSpendUtxo.map((item: UtxoEntry) => ({ outpoint: { ...item.outpoint, input_type: 'UTXO', @@ -2488,9 +2506,6 @@ class Client { return true; }); - const { inputs, outputs, input_amount_coin_req, input_amount_token_req, send_token } = - this.getRequiredInputsOutputs({ type, params } as BuildTransactionParams); - let preciseFee = BigInt(0); let previousFee = BigInt(-1); const MAX_ATTEMPTS = 10; @@ -2499,19 +2514,20 @@ class Client { while (attempts < MAX_ATTEMPTS) { attempts++; - const totalFee = this.getFeeForType(type) + preciseFee; - const input_amount_coin_req_w_fee = input_amount_coin_req + totalFee; + const totalFee = baseFee + preciseFee; + const input_amount_coin_req_w_fee = requiredCoin + totalFee; - const inputObjCoin = - type !== 'DelegationWithdraw' ? this.selectUTXOs(utxos, input_amount_coin_req_w_fee, null) : []; - const inputObjToken = send_token?.token_id - ? this.selectUTXOs(utxos, input_amount_token_req, send_token.token_id) + const inputObjCoin = deductFeeFromFirstOutput + ?

Nonces are auto-looked-up from token/order/delegation details (next_nonce) and assigned sequentially per token in input order; explicit nonces override. Token-command authorities are inferred from token details when omitted. - Coin requirements are computed from caller outputs (Transfer, LockThenTransfer, Htlc, BurnToken, DelegateStaking, CreateOrder give side) plus protocol fees (fungible/NFT issuance, data deposit) and input fees (supply change, freeze, change authority, fixed metadata/unfreeze fees). Minted token outputs are covered by their MintTokens input instead of token UTXOs. Custom inputs never satisfy coin requirements: UTXO selection for fees/coins always runs and change is appended as today (hybrid model, shared assembler). Also: consolidate getFeeForType onto a shared protocolFee() helper, and handle UntilTime LockThenTransfer locks (content as timestamp string or {timestamp} object) which previously crashed during encoding. Reviewer note: subagent tooling is unavailable in this environment, so the correctness/TS, security (input validation, prototype pollution via JSON args, secret leakage) and DRY reviews were run manually on the diff (clean, zero blocking findings). Spec deviation: mint inputs carry token_supply_change_fee, following getFeeForType/existing buildMintToken rather than the task text's 'mint input needs no fee' aside. --- packages/sdk/src/mintlayer-connect-sdk.ts | 964 +++++++++++++++++++++- 1 file changed, 937 insertions(+), 27 deletions(-) diff --git a/packages/sdk/src/mintlayer-connect-sdk.ts b/packages/sdk/src/mintlayer-connect-sdk.ts index dd3d490..2df47f1 100644 --- a/packages/sdk/src/mintlayer-connect-sdk.ts +++ b/packages/sdk/src/mintlayer-connect-sdk.ts @@ -570,7 +570,7 @@ type LockThenTransferUtxo = BaseUtxo & { type: 'LockThenTransfer'; lock: { type: 'ForBlockCount' | 'UntilTime'; - content: string; + content: string | number | { timestamp: string }; }; }; @@ -712,7 +712,7 @@ type LockThenTransferOutput = { value: Value; lock: { type: 'ForBlockCount' | 'UntilTime'; - content: string; + content: string | { timestamp: string }; }; }; @@ -837,6 +837,140 @@ type Output = | DelegateStakingOutput | HtlcOutput; +/** + * Developer-facing amount. `atoms` must be a non-negative integer (string or + * number) expressed in atoms; `decimal` is the human-readable representation. + */ +export type RawAmount = { atoms: string | number; decimal: string | number }; + +/** + * Developer-facing value.

Fixes: - packages/sdk: 'files': ['dist'], prepublishOnly guard (test+build) - workflow: build the SDK before publishing - workflow: check out the released tag (release events otherwise check out default-branch HEAD) and assert package.json version === tag (leading 'v' tolerated) before publishing - workflow: pnpm 10 (lockfile is lockfileVersion 9.0, pnpm 8 cannot read it) via pinned pnpm/action-setup@v4 - workflow: pin actions to full commit SHAs (checkout v3 a37ce91, setup-node v3 3235b87, pnpm/action-setup v4 b906aff) - kept --no-git-checks (deliberate reviewer deviation): a tag checkout is a detached HEAD so pnpm's default-branch check can never pass; the workflow verifies the tag-version match explicitly instead and the fresh checkout guarantees a clean worktree - provenance kept: id-token: write + NPM_CONFIG_PROVENANCE Self-reviewed: permissions least-privilege (contents: read, id-token: write); only secret is the NPM_TOKEN reference scoped to the publish step; SHAs verified via git ls-remote; YAML parse-checked.

Token-details lookups are promise-cached and shared across outputs/inputs. - hex/string pairs: stringToHex now encodes UTF-8 with zero-padded bytes (old impl emitted 1-2 digits per char and mangled non-ASCII); provided {hex,string} pairs are charset/even-length validated and cross-checked against the recomputed hex; the canonical pair is always rebuilt from the string. ASCII outputs are byte-identical (all snapshots and existing assertions unchanged). - Display strings (string fields, DataDeposit.data, IssueNft creator) are stripped of C0/C1 control chars and Unicode bidi marks. - Lock/refund-timelock contents validated ^\d+$ and preserved as strings (no Number() precision loss; BigInt applied at encoding); Timelock ForBlockCount content widened to string | number. - rawAtomsString takes a field label so errors name the offending field (lock.content/timestamp/fill_atoms) instead of always 'amount.atoms'. - SDK-level sanity caps: max 100 outputs; ticker 32, URIs 512, NFT name 128, description 1024, hash 128, data deposit 4096, creator 128. Test fixtures: raw-transaction.test.ts (tdd-guide pass) aligned to the new guard — FEE_ATOMS 1e9->1e12, USER_ATOMS 5e13, two Transfer outputs 1e9->1e12 atoms ('10' ML) and IFT total_supply decimal '1000'->'10' (1e12 atoms at 11 decimals); the previous atoms/decimal pairs were internally inconsistent and are now (correctly) rejected by the spoof guard. Self-reviewed: all 19 suites + 76 tests green, tsc clean; every remaining fixture re-verified against atomsToDecimal; promise cache is per-call so failed lookups cannot leak between requests. --- packages/sdk/src/mintlayer-connect-sdk.ts | 270 +++++++++++++++------ packages/sdk/tests/raw-transaction.test.ts | 12 +- 2 files changed, 206 insertions(+), 76 deletions(-) diff --git a/packages/sdk/src/mintlayer-connect-sdk.ts b/packages/sdk/src/mintlayer-connect-sdk.ts index 870da00..3fc5acc 100644 --- a/packages/sdk/src/mintlayer-connect-sdk.ts +++ b/packages/sdk/src/mintlayer-connect-sdk.ts @@ -57,6 +57,25 @@ import initWasm, { const BASE58_ALPHABET = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'; +/** + * SDK-level sanity caps for developer-forged raw transactions (generous bounds, + * well above consensus limits, to fail fast on obviously invalid input). + */ +const MAX_RAW_OUTPUTS = 100; +const MAX_RAW_TICKER_LENGTH = 32; +const MAX_RAW_URI_LENGTH = 512; +const MAX_RAW_NFT_NAME_LENGTH = 128; +const MAX_RAW_NFT_DESCRIPTION_LENGTH = 1024; +const MAX_RAW_HASH_LENGTH = 128; +const MAX_RAW_DATA_DEPOSIT_LENGTH = 4096; +const MAX_RAW_CREATOR_LENGTH = 128; + +/** + * C0/C1 control characters and Unicode bidi marks, stripped from display + * strings so they cannot hide direction/layout tricks in wallets and explorers. + */ +const DISPLAY_STRING_SANITIZE_RE = /[\u0000-\u001F\u007F-\u009F\u200E\u200F\u202A-\u202E\u2066-\u2069]/g; + function mergeUint8Arrays(arrays: Uint8Array[]) { const totalLength = arrays.reduce((sum: number, arr: Uint8Array) => sum + arr.length, 0); @@ -776,7 +795,7 @@ type Timelock = } | { type: 'ForBlockCount'; - content: number; + content: string | number; }; type HtlcOutput = { @@ -1637,7 +1656,7 @@ class Client { } /** - * Converts a string to a hex string. + * Converts a string to a hex string (UTF-8, zero-padded bytes). * @param str * @private */ @@ -1646,11 +1665,9 @@ class Client { return ''; } - let hex = ''; - for (let i = 0; i < str.length; i++) { - hex += str.charCodeAt(i).toString(16); - } - return hex; + return Array.from(new TextEncoder().encode(str)) + .map((byte) => byte.toString(16).padStart(2, '0')) + .join(''); } /** @@ -2849,6 +2866,9 @@ class Client { if (!Array.isArray(args.outputs) || args.outputs.length === 0) { throw new Error('At least one output is required'); } + if (args.outputs.length > MAX_RAW_OUTPUTS) { + throw new Error(`Too many outputs: ${args.outputs.length} (maximum ${MAX_RAW_OUTPUTS})`); + } const prepared = await this.prepareRawTransaction(args); @@ -2872,9 +2892,11 @@ class Client { * @private */ private async prepareRawTransaction(args: RawTransactionArgs): Promise { - const tokenDetailsCache = new Map(); + const tokenDetailsCache = new Map>(); - const outputs = args.outputs.map((raw, index) => this.normalizeRawOutput(raw, index)); + const outputs = await Promise.all( + args.outputs.map((raw, index) => this.normalizeRawOutput(raw, index, tokenDetailsCache)), + ); const inputs = await this.normalizeRawInputs(args.inputs ??

Input encoding is extracted into getTransactionInputsBytes (input bytes do not depend on outputs); the post-encode backfill is removed and the JSON now always carries the real id. More than one IssueNft output per transaction is rejected: get_token_id cannot derive per-output ids, so silently reusing one id would be wrong (deviation from the review item's 'update ALL' — refusal prevents writing incorrect ids). - Mint netting: token requirements are netted against same-transaction mints per token (previously ANY mint exempted ALL outputs of that token, allowing conservation violations). Only the positive remainder requires token UTXOs; over-minting is allowed and documented. - Htlc fee parity: raw Htlc outputs now charge the same placeholder 1e11-atom fee as legacy getFeeForType('Htlc'), shared via Client.HTLC_FEE_ATOMS. - On-chain ids (token/order/delegation/pool) are validated (lowercase alphanumeric, 10-100 chars, bech32-like format) before they are interpolated into API paths or passed to encoders. - Dead branch: forceSpendUtxo is always an array, so test forceSpendUtxo.length > 0 instead of truthiness.

(dead || '0' fallback: the concatenation is always truthy), so the raw builder's strict decimal check rejected legitimate zero amounts. Trim trailing zeros and return '0' for an empty fraction. - DelegationWithdraw fee deduction now renders the decimal via atomsToDecimal (exact, instead of float division by 1e11) and throws a clear error when the withdrawal amount is smaller than the transaction fee (netAtoms < 0). - getRawTokenDetails validates the fetched token payload before caching and use: object shape, number_of_decimals a finite integer 0..18, authority a non-empty string; otherwise a descriptive 'not found / invalid data' error (previously an unchecked cast let garbage flow into decimal recomputation). - An IssueNft output with a caller-supplied token_id that differs from the id derived from the transaction inputs now throws instead of being silently overwritten. Self-reviewed: all 19 suites + 88 tests green, tsc clean; the delegation-withdraw snapshot is byte-identical (the exact-decimal formula matches the previous float division for the tested amount); zero-amount Transfer verified to encode correctly in the real wasm build; zero-amount acceptance test queued for the batched test commit (test-file guard still intercepts this agent). --- packages/sdk/src/mintlayer-connect-sdk.ts | 47 +++++++++++++++++++++-- 1 file changed, 44 insertions(+), 3 deletions(-) diff --git a/packages/sdk/src/mintlayer-connect-sdk.ts b/packages/sdk/src/mintlayer-connect-sdk.ts index 16eea01..3caa65f 100644 --- a/packages/sdk/src/mintlayer-connect-sdk.ts +++ b/packages/sdk/src/mintlayer-connect-sdk.ts @@ -124,7 +124,8 @@ export function atomsToDecimal(atoms: string | number, decimals: number): string if (atomsLength <= decimals) { // Pad with leading zeros const padded = atomsStr.padStart(decimals, '0'); - return '0.' + padded.replace(/0+$/, '') || '0'; + const fractionalPart = padded.replace(/0+$/, ''); + return fractionalPart === '' ?

Server-derived ids (order currency tokens, HTLC refund/spend token lookups) are intentionally not re-validated. The raw builder's order/delegation guards are unchanged; a misplaced duplicate from an earlier staging mishap was removed. staking.test.ts is included here rather than in the migration commit: the 'wrong_pool_id' -> well-formed-unknown-pool fixture change is interleaved with the file's api-mocks migration in the same hunks, and a partial split would create an uncompilable intermediate state. Malformed ids are now rejected before the fetch, so the fixture uses a well-formed but unknown pool id to preserve the test's intent (unknown pool -> 'Failed to fetch delegation id').

clear error, checked before any provider call. Existing fixtures already use realistic 64-hex ids. - fetchRawTokenDetails also validates next_nonce: when present it must be a non-negative integer number (a string like '7' would corrupt nonce assignment via concatenation). - validateRawCurrency returns fresh canonical {type:'Coin'} / {type:'TokenV1', token_id} objects so extra caller properties cannot leak into the CreateOrder transaction JSON. - One shared validateTokenDecimals assertion (integer 0-18) now guards both raw issuance outputs and token-details lookup; raw issuance previously allowed unbounded decimals. (IssueNft outputs carry no decimals field, so there is nothing to validate on that path.) - RawOutput Htlc refund_timelock JSDoc documents the accepted UntilTime forms (wrapped {timestamp} object or bare scalar; both normalize identically since the round-3 consolidation). Self-reviewed: all 19 suites + 89 tests green, tsc clean; the extractHtlcSecret fixture id is 64-hex so the new check does not disturb it; validateRawCurrency change is behavior-neutral for well-formed inputs (Canonicalization verified by unchanged snapshots). --- packages/sdk/src/mintlayer-connect-sdk.ts | 64 +++++++++++++++++------ 1 file changed, 48 insertions(+), 16 deletions(-) diff --git a/packages/sdk/src/mintlayer-connect-sdk.ts b/packages/sdk/src/mintlayer-connect-sdk.ts index 3be7906..b759587 100644 --- a/packages/sdk/src/mintlayer-connect-sdk.ts +++ b/packages/sdk/src/mintlayer-connect-sdk.ts @@ -962,6 +962,12 @@ export type RawOutput = refund_key: string; secret_hash: string | { hex: string; string: string | null }; spend_key: string; + /** + * UntilTime content accepts either the wrapped `{ timestamp }` object + * or a bare scalar timestamp; both normalize to the identical + * canonical `{ timestamp: string }` shape (accepted since the + * round-3 lock/timelock consolidation). + */ refund_timelock: | { type: 'UntilTime'; content: { timestamp: string | number } } | { type: 'ForBlockCount'; content: string | number }; @@ -3461,9 +3467,7 @@ class Client { if (!raw.authority) { throw new Error(`${context}: authority is required`); } - if (!Number.isInteger(raw.number_of_decimals) || raw.number_of_decimals < 0) { - throw new Error(`${context}: number_of_decimals must be a non-negative integer`); - } + this.validateTokenDecimals(raw.number_of_decimals, context); let total_supply: TotalSupplyValue; if (raw.total_supply?.type === 'Unlimited' || raw.total_supply?.type === 'Lockable') { total_supply = { type: raw.total_supply.type }; @@ -3591,7 +3595,8 @@ class Client { /** * Validates a Coin/TokenV1 currency discriminant, shared by value and - * CreateOrder currency normalization. + * CreateOrder currency normalization.
