In this release

This release is an accumulation of all previous 1.4.x releases. Now it's available for Mainnet.
After the activation of the feature #17 all Protocol changes become available.

Protocol Enhancements

Added support for Ethereum transactions that perform token transfers or dApp script invocations. Thanks to this, MetaMask users can sign transactions and send them to the Waves blockchain. More details
Added support for orders with ECDSA signature in Exchange transactions. Thanks to this, users can sign orders with MetaMask. More details
Added the priceMode parameter of order version 4. The parameter enables price mode similar to order version 3.
Changed the minimum fee for a Set Script transaction: now the minimum fee depends on the script size.
Weak public keys can no longer be used to sign transactions.

Ride

Issued version 6 of the Ride Standard library.
The maximum complexity of a callable function of a dApp script in Standard library version 6 is changed to 52 000.
The maximum total complexity of all callable functions and asset scripts within a transaction depends on the version of Standard library in the first dApp script invoked:
- If the first dApp script uses version 6, the total complexity is limited by 52 000.
- If the first dApp script uses version 5, the total complexity is limited by 26 000. If script version 6 functions are invoked next, their complexity can exceed 10,000 and is limited only by the total complexity of the transaction.
The sender's account script complexity is not included in that limit.
New complexity estimation rules reduce overall script complexity.
The maximum size of a dApp script is increased to 160 Kbytes regardless of the Standard library version.
The maximum total number of ScriptTransfer, Lease, LeaseCancel script actions executed by all callable functions in a single transaction is 100.
The maximum total number of Issue, Reissue, Burn, SponsorFee script actions executed by all callable functions in a single transaction is 30.
Callable functions no longer accept arguments of type Union.
Added the following built-in functions:
- sqrt(Int,Int,Int,Union)
- sqrt(BigInt,Int,Int,Union)
Changed the limitation on the second parameter of drop, dropRight, take, takeRight string functions and byte array functions.
Changed the limitations on input and output data size for the built-in string functions makeString and split; their complexity reduced to 1. Added the range of similar functions with different complexity depending on the data size.
Changed the complexity of certain built-in functions. The complexity is given in the [Ride v6] Built-in functions article.
Introduced a limit on the total number of payments attached to dApp script invocations in a single transaction: a maximum of 100. The limit does not depend on the Standard library versions used.

Node REST API

Breaking Changes

Added support for Ethereum transactions that perform token transfers or dApp script invocations. JSON representation of a transaction depends on its content:

Features of the Ethereum transaction JSON representation:

sender contains Waves address base58 encoded,
senderPublicKey is 64 bytes base58 encoded,
bytes contains the entire Ethereum transaction bytes, including the ECDSA signature, HEX encoded.
proofs array is missing.

Added support for Exchange transactions containing an order (or both orders) with an ECDSA signature.

}

Features JSON representation of an order with ECDSA signature:

sender contains Waves address base58 encoded,
senderPublicKey is 64 bytes base58 encoded,
eip712Signature contains an ECDSA signature HEX encoded,
proofs array is missing.

Activation

To activate the improvements listed above, vote for feature #17 “Ride V6, MetaMask support”. The next voting interval starts at height 3160001 (at around 09:30 UTC on June, 13th)

Update Notes

Blockchain Updates users will need to update their clients and reimport blockchain to rebuild BU database so that new order metadata is available.
All Testnet & Stagenet nodes must be updated to version 1.4.6, otherwise they may end up on a fork.
