🔷 [Epic] NEAR accounts can control Top 20 chains

[gagdiez]

Background

NEAR accounts can control foreign accounts through Chain Abstraction's MPC service. We need to ensure that users can control accounts on the top 20 chains based on market cap and usage.

More importantly, developers should be able to understand very easily how to control foreign accounts and be able to go multi-chain in less than a week of work.

To add a new chain please make a PR to https://github.com/NearDeFi/chainsig.js to add support for a new chain, next update this repo, and then add the code snippets to the docs.

For non smart contract chains the only required example is a transfer, for smart contract chains please add a function call to a counter example.

Chains to add support for:

• EVM (add different EVMs, BNB smart chain, Avalanche, Polygon, Arbitrum, ZK sync, Berachain, Linea, Unichain, Aurora)
• Solana (add function call).
• Cosmos (already supported in chainsig.js)
• XRP
• Sui
• Aptos
• Ton
• Doge
• Litecoin
