graph, runtime: Add ethereum.decodeParams host function#6649
Merged
Conversation
ethereum.decode decodes its input as a single ABI value, which fails for calldata/event data whose top-level type is a tuple with a dynamic field (e.g. Gnosis Safe execTransaction): such data is encoded as ABI function parameters and has no leading offset word. Add ethereum.decodeParams, which decodes via abi_decode_params, and gate it behind api version 0.0.10. ethereum.decode is left unchanged. Fixes #5432

There was a problem hiding this comment.
It would be nice if we needed only one host function, i.e., if we could use ethereum.decode for both, but if not, this is a nice enhancement

ethereum.decodedecodes input as a single ABI value, which fails on calldata/event data whose top-level type is a dynamic tuple (e.g. Gnosis
execTransaction)— that data is ABI parameter-encoded, with no leading offset word.
Adds
ethereum.decodeParams(usesabi_decode_params), gated behind apiVersion0.0.10.
ethereum.decodeis unchanged, so no deployed subgraph is affected.graph-ts binding: graphprotocol/graph-tooling#2143. Integration test to follow
once graph-ts publishes.
Fixes #5432
