Smart Contract Abstractions!

New features

New smart contract methods abstraction. Allows developers to load a smart contract's parameters, and get a contract object with methods that correspond to the smart contract params.

const contract = await Tezos.contract.at('KT1SawqvsVdAbDzqc4KwPpaS1S1veuFgF9AN');
console.log(Object.keys(contract.methods));
// { transfer: [Function: method],
//  approve: [Function: method],
//  getAllowance: [Function: method],
//  getBalance: [Function: method],
//  getTotalSupply: [Function: method],
//  setPause: [Function: method],
//  setAdministrator: [Function: method],
//  getAdministrator: [Function: method],
//  mint: [Function: method],
//  burn: [Function: method] }
const op = await contract.methods.mint("tz1QZ6KY7d3BuZDT1d19dUxoQrtFPN2QJ3hn", 100).send({ gasLimit: 200000 })
await op.confirmation();

See the example/ directory for an example.

New signer package that provides a signer API

TezBridge supported is implemented for signing operations.

Note that accounts must be revealed to originate or call smart contracts. Because TezBridge does not allow direct exposure of the public key.

Other changes

Add contract origination example

Add get manager key support to rpc package.

Error response now allows access to the raw request body
