The day has finally arrived. NEAR Protocol’s Chain Signatures technology is live on mainnet. We are ready to move forward together towards a future of chain abstraction. It’s time to remove barriers to entry, liquidity, and usability.

Detailed explanation of chain signature technology

Chain signature technology allows users to sign any transaction on any blockchain directly using their NEAR account.

On August 8, 2024, ChainSignature will be released for Bitcoin, Ethereum (and any EVM chain), Dogecoin, XRP, Cosmos, Polkadot, etc., supporting all ECDSA (Elliptic Curve Digital Signature Algorithm) based blockchains. It will be released for Solana and more chains soon.

Using chain signature technology, you can:

Interact with (almost) any chain using your NEAR account

Unlocking bridge-free full-chain DeFi

Launch a full-chain token — issuing a token on multiple chains, etc.

Projects and public chains that already support chain signatures

There are dozens of teams currently using NEAR’s chain signature technology. Let’s take a look at a few of them:

· Please

Leverage AI to build and execute cross-chain transactions. Compatible with any chain's Passkey wallet, and directly connect to all Ethereum applications through WalletConnect. This is what Bitte does.

· Sweat Economy

Sweat Economy is one of the world's leading consumer Web3 applications, paving the way for the future of chain abstraction. Sweat users will be able to use any chain supported by the Sweat wallet and pay fees with SWEAT tokens. The first chains compatible with Sweat Economy are BNB Chain and Base.

· DeFuse

DeFuse is a true multi-chain spot DEX (decentralized exchange). Trades between any assets on any chain are completed in seconds. Enjoy the most liquidity and the best prices. No fees are charged.

· Allstake

Allstake is the first full-chain grid staking protocol that supports native re-staking of BTC, SOL, NEAR, etc.

· HERE Wallet

HERE Wallet is the creator of HOT Protocol, one of the most used Web3 dApps. HERE Wallet is a Telegram-based wallet with over 1 million daily active users. Access any chain directly through Telegram.

A non-exhaustive list of chain signature compatible chains is as follows:

Bitcoin

Ethereum (and standard EVM L2s)

BNB

Ripple

Tron

Polka Dot

Polygon

Avalanche

Cosmos

Ivy

Filecoin

Internet Computer

Mantle
