The library simplifies development of dApps that interact with smart contracts in SKALE infrastructure.
- resolving of addresses of SKALE contracts on different networks
- providing up to date ABI for SKALE contracts (they may change over time due to upgradeable nature of some contracts)
- automatic creation of
Contractobjects.
yarn add @skalenetwork/skale-contracts-ethers-v6Main abstractions used by the library is provided below:
Represents blockchain where smart contracts are deployed.
It could be Ethereum mainnet, goerli, SKALE chain or similar ethereum compatible chains
SKALE smart contracts grouped into projects to serve particular purpose.
Examples of projects are IMA, skale-manager or etherbase.
An instance is a particular project deployed to a particular network.
For example IMA on Ethereum mainnet or etherbase on some of SKALE chains.
An alias is a textual name of an instance.
The library provides master object skaleContracts.
This object is used to provide desired network, project and instance using it's alias or direct address.
When target instance is received it can be queried for information (address, ABI or Contract object) about a particular contract by it's name.
