This release adds full Avalanche support and tightens fee estimation across UTXO and EVM with a new missingFunds field, a gasEstimationFailed flag, and far more realistic estimates for token and NFT transfers. EVM connectors can now also send several transactions back-to-back without colliding on the nonce.

This release adds address validation across all networks, custom UTXO transactions with explicit inputs and outputs, improvements to the fee API, and removes heavy third-party dependencies in favor of native implementations.

ChainGate 1.0 is the first TypeScript SDK that lets you create wallets, sign transactions, query balances, and explore blockchain data across every major network — with a single, unified API. No ethers.js. No chain-specific boilerplate. Just npm install chaingate and you're building.

This isn't a minor version bump — it's a complete rewrite from the ground up. New wallet architecture, new connector system, new transaction pipeline, native crypto signing, and first-class support for both EVM and UTXO chains. If you've been looking for a single library to replace your patchwork of blockchain tools, this is it.

We're kicking off 2026 with a big upgrade: Fantom has evolved into Sonic, and every network on ChainGate now exposes detailed native token information directly in the API. Less guesswork, more data, fewer API calls.

The /global/networksInfo endpoint now returns market data alongside network status, and we've added support for 20+ new EVM networks.

Previously, you needed to call both /global/markets and /global/networksInfo to get complete network information. Now everything is unified in a single response.

We've added a new endpoint that returns network status for all supported EVM chains in a single request.

Previously, you needed to call /{network}/networkStatus separately for each network. Now you can get all network data at once with /global/networksInfo.

Big news: ChainGate just got its biggest upgrade yet.

Version 0.6.0 delivers a full internal restructuring, setting the foundation for the upcoming 1.0 release — along with a cleaner API, improved performance, and initial support for React apps.

ChainGate API v0.21 introduces new dedicated block endpoints for EVM and UTXO networks. These are more powerful, standardized, and ready for modern applications.

You asked for it — and it's here.
Fiat currency support is now fully integrated into the ChainGate SDK.

Previously, fiat pricing was only available through the /global/markets API. Now, you can use fiat values directly within your wallet logic, including balance display, transfers, and conversions — all using simple, familiar fiat codes like usd, eur, gbp, and more.

We’ve just added a new endpoint to the ChainGate API: /global/markets!

You can now retrieve real-time exchange rates for both cryptocurrencies and fiat currencies, all expressed in USD.
Whether you're tracking Bitcoin, Ethereum, EUR, or JPY, this new endpoint gives you reliable pricing and 24h volume data to power your apps, dashboards, or trading logic.
