An ABI to be retrieved over HTTP(S).

Etherscan(Address)

An address of a mainnet contract that has been verified on Etherscan.io.

Polygonscan(Address)

An address of a mainnet contract that has been verified on Polygonscan.com.

Snowtrace(Address)

An address of a mainnet contract that has been verified on snowtrace.io.

Npm(String)

The package identifier of an npm package with a path to a Truffle artifact or ABI to be retrieved from unpkg.io.

Implementations

Parses an ABI from a source

Contract ABIs can be retrieved from the local filesystem or online from etherscan.io. They can also be provided in-line. This method parses ABI source URLs and accepts the following:

  • raw ABI JSON

  • relative/path/to/Contract.json: a relative path to an ABI JSON file. This relative path is rooted in the current working directory. To specify the root for relative paths, use Source::with_root.

  • /absolute/path/to/Contract.json or file:///absolute/path/to/Contract.json: an absolute path or file URL to an ABI JSON file.

  • http(s)://... an HTTP url to a contract ABI.

  • etherscan:0xXX..XX or https://etherscan.io/address/0xXX..XX: a address or URL of a verified contract on Etherscan.

  • npm:@org/package@1.0.0/path/to/contract.json an npmjs package with an optional version and path (defaulting to the latest version and index.js). The contract ABI will be retrieved through unpkg.io.

Creates a local filesystem source from a path string.

Creates an HTTP source from a URL.

Creates an Etherscan source from an address string.

Creates an Polygonscan source from an address string.

Creates an Snowtrace source from an address string.

Creates an Etherscan source from an address string.

Retrieves the source JSON of the artifact this will either read the JSON from the file system or retrieve a contract ABI from the network depending on the source type.
