@subsquid/evm-typegen

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.

Usage

``
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 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.

squid-evm-typegen src/abi 0xBB9bc244D798123fDe783fCc1C72d3Bb8C189413#contract
