Release Note

Release Note v5.3.1

• Fix getBlockRange() error for range of 1 (#398).
• Add support for estimateenergy in TransactionBuilder#deployConstantContract() API.

Release Note v5.3.0

There are several changes and new features in this version. First, we upgrade the implementation of elliptic curves algorithm, which means we replace elliptic module to ethereum-cryptography. Besides, we also bump ethers lib to 6.x which will take a little break changes to several APIs. For example, fromMnemonic will not receive a string as the wordlist value but replaced by an WordList object. See more in https://docs.ethers.org/v6/api/wordlists/#Wordlists. Ethers also imports BigInt so you may need to upgrade your browser to a satisfied version. In summary, here is the change log:

• Replace elliptic with ethereum-cryptography/secp256k1
• Bump ethers to ^6.6.0
• Optimize argument validation for createToken, updateToken and applyForSR
• callValue and tokenValue can both be 0 when the contract constructor is payable. createSmartContract
• Support shouldPollResponse to customize poll times (#368)
• Support Tip541 by transactionBuilder.cancelUnfreezeBalanceV2
• Support Tip542 by adding a parameter in transactionBuilder.delegateResource
• Support for estimating the energy used in contract deployment by transactionBuilder.deployConstantContract

    'ethereum-cryptography/secp256k1': require.resolve('ethereum-cryptography/secp256k1.js')
}

• Module not found: Error: Can't resolve 'crypto'

Solution: add a fallback config in your webpack config, and npm install crypto-browserify

}
