v2.0.0-rc.4

Common

• Add sf.firehose.v2.EndpointInfo/Info service on Firehose and sf.substreams.rpc.v2.EndpointInfo/Info to Substreams endpoints. This involves the following new flags:
  • advertise-chain-name Canonical name of the chain according to https://thegraph.com/docs/en/developing/supported-networks/ (required, unless it is in the "well-known" list)
  • advertise-chain-aliases Alternate names for that chain (optional)
  • advertise-block-features List of features describing the blocks (optional)
  • advertise-block-id-encoding Encoding format of the block ID [BLOCK_ID_ENCODING_BASE58, BLOCK_ID_ENCODING_BASE64, BLOCK_ID_ENCODING_BASE64URL, BLOCK_ID_ENCODING_HEX, BLOCK_ID_ENCODING_0X_HEX] (required, unless the block type is in the "well-known" list)
  • ignore-advertise-validation Runtime checks of chain name/features/encoding against the genesis block will no longer cause server to wait or fail.

Substreams

• add --common-tmp-dir flag and activate local caching of pre-compiled WASM modules through wazero feature
• revert module hash calculation from v1.5.5, when using a non-zero firstStreamableBlock. Hashes will now be the same even if the chain's first streamable block affects the initialBlock of a module.
• add --substreams-block-execution-timeout flag (default 3 minutes) to prevent requests stalling
