Using Agent Cash

Caishen SDK provides the only wallets which support gasless stablecoin swaps, powered by Agent Cash.

Cash is a chain-abstracted, gasless stablecoin system designed to make stablecoin transfers seamless, fast, and free.

🔍 What is Cash?

Cash is an internal ERC-20-compatible asset that abstracts away the complexity of stablecoins across chains. It enables instant, gasless transfers between wallets without needing users to worry about:

  • Native gas tokens (e.g., ETH, MATIC)

  • Stablecoin formats (e.g., USDC vs USDT)

  • Blockchain networks (e.g., Arbitrum, Base, Solana)

🧪 How It Works

  • Deposit: Users deposit supported stablecoins (e.g., USDC, USDT) from chains like Arbitrum, Base, or Solana.

  • Issue: The system issues equivalent Cash tokens 1:1, held in an abstracted balance.

  • Send: These Cash tokens can be sent to any wallet address instantly with zero gas cost.

  • Withdraw: When users withdraw, their Cash tokens are burned and they receive the original stablecoin on the selected chain.

⚠️ Different combinations of agentId and userId result in separate Cash balances.

✅ Benefits

  • 💸 Gasless transfers (no ETH/SOL required)

  • ⚡ Cross-chain abstraction

  • 🔄 Simple send/receive interface

  • 🔐 Fully backed, 1:1 redeemable
