Summary

This release of Taquito supports the upcoming Hangzhou protocol. As usual, this version supports the current protocol, Granada, and the next protocol Hangzhou.

We encourage all developers to update their projects to use version Taquito v11 as soon as is practical and absolutely before the Tezos mainnet transition from Granada to Hangzhou.

Important note:

Please note that the Michelson-Encoder does not support the global constant in this current release (11.0.0-beta). The expanded contract scripts need to be used with the Michelson-Encoder until further support. This brings the following limitation: only the 'init' property can be used if you want to originate a contract having a global constant in the storage section of its code. Do not use the storage property, which depends on the Michelson-Encoder.

Here an example:

const op = await Tezos.contract.originate({
  code: [
    { prim: 'parameter', args: [ ...] },
    { prim: 'storage', args: [{ prim: 'constant', args: [{ string: 'expr...' }] }] },
    { prim: 'code', args: [ ... ] } ],
  init: // The storage property can't be used until global constants are supported in by the Michelson-Encoder. Please use the `init` property instead.
});

@taquito/taquito - Support the new operation kind register_global_constant on the contract, batch and estimate APIs

The new manager operation register_global_constant has been added to the contract, batch, and estimate APIs. This new operation allows users to register Micheline expressions in a global table of constants.

A registerGlobalConstant method is available on the ContractProvider class. A value representing the Micheline expression to register in its JSON format is required as a parameter. The registerGlobalConstant method returns an instance of RegisterGlobalConstantOperation containing a globalConstantHash member that corresponds to the index(hash) of the newly registered constant.

const op = await Tezos.contract.registerGlobalConstant({
    value: { "prim": "or",
                "args":
                  [ { "prim": "int", "annots": [ "%decrement" ] },
                    { "prim": "int", "annots": [ "%increment" ] } ] }
    });
await op.confirmation();
const hash = op.globalConstantHash; // expr...

After registering an expression as a global constant, the occurrences of this expression in a smart contract code can be replaced by its corresponding hash, allowing users to originate larger contracts. More details about the new global constant feature and examples using the batch API are available on the following documentation page: https://tezostaquito.io/docs/global_constant

@taquito/michelson-encoder - Support new types related to operations-on-timelock

New tokens (ChestToken and ChestKeyToken) have been implemented in the Michelson-encoder package to support the new types chest and chest_key and allow data conversion between Michelson and js.

@taquito/utils - Provide utility to verify signatures

Taquito provides a function named verifySignature that allows verifying signatures of payloads. The function takes a message, a public key, and a signature as parameters and returns a boolean indicating if the signature matches.
The crypto library stablelib is used instead of libsodium in order not to drastically increase the bundle size of the @taquito/utils package.

Here is an example of use:

import { verifySignature } from '@taquito/remote-signer';

const message = '03d0c10e3ed11d7c6e3357f6ef335bab9e8f2bd54d0ce20c482e241191a6e4b8ce6c01be917311d9ac46959750e405d57e268e2ed9e174a80794fbd504e12a4a000141eb3781afed2f69679ff2bbe1c5375950b0e40d00ff000000005e05050505050507070100000024747a32526773486e74516b72794670707352466261313652546656503539684b72654a4d07070100000024747a315a6672455263414c42776d4171776f6e525859565142445439426a4e6a42484a750001';
const pk = 'sppk7c7hkPj47yjYFEHX85q46sFJGw6RBrqoVSHwAJAT4e14KJwzoey';
const sig = 'spsig1cdLkp1RLgUHAp13aRFkZ6MQDPp7xCnjAExGL3MBSdMDmT6JgQSX8cufyDgJRM3sinFtiCzLbsyP6d365EHoNevxhT47nx'

await verifySignature(message, pk, sig);

@taquito/rpc - Support for the RPC endpointcontext/contracts/{contract}/script/normalized

A new method on the RpcClient named getNormalizedScript is available. If global constants are present in the code of a smart contract, getNormalizedScript returns the expanded script. In contrast, the global constants are not expanded in the response provided by the getScript method.

Internally in Taquito, the usage of getScript has been replaced by getNormalizedScript to ensure that all script passed to the Michelson-Encoder won't contain global constant because the Michelson-Encoder does not support the global constant in this current release (11.0.0-beta).

Preliminary support for Idiazabalnet protocol

This release includes preliminary support for the Idiazabal protocol to allow early testing.
Please note the following:

  • The protocol constant cost_per_byte is mistakenly set to 1000 instead of 250. Meaning that storage costs are higher than on the precedent testnet until this is fixed in the next I network.
  • The Endorsement operation has new required properties slot, round and block_payload_hash that are not yet supported in the @taquito/local-forging package.
  • The RPC context/delegates/${address} has new properties that are not yet supported in the @taquito/rpc package.

What's coming next for Taquito?

We plan to provide abstractions for some of the new Hangzhou features. For example, an addition to the ContractAbstration will allow running on-chain views and an abstraction that will make using the new timelock feature easier.
