Generates TypeScript facades for EVM transactions, logs and eth_call queries.
The generated facade classes are assumed to be used by squids indexing EVM data. The generated classes depend on ethers.
npm i -g @subsquid/evm-typegen
Arguments:
output-dir output directory for generated definitions
abi ABI file
Options:
--multicall generate facade for MakerDAO multicall contract
--etherscan-api <url> etherscan API to fetch contract ABI by a known address
--clean delete output directory before run
-h, --help display help for command
ABI file can be specified in three ways:
1. as a plain JSON file:
squid-evm-typegen src/abi erc20.json
2. as a contract address (to fetch ABI from etherscan)
squid-evm-typegen src/abi 0xBB9bc244D798123fDe783fCc1C72d3Bb8C189413
3. as an arbitrary http url
squid-evm-typegen src/abi https://example.com/erc721.json
In all cases typegen will use ABI's basename as a basename of generated files.
You can overwrite basename of generated files using fragment (#) suffix.
