FAQPage Schema
How do I enable non-custodial wallet management for AI agents?▼

Non-custodial wallet management for AI agents is enabled through a fully-documented REST/SDK interface. This allows automated workflows to create wallets, query balances, and execute off-chain signing without surrendering custodianship of the funds.

What is cross-chain escrow and how does it work with crypto payments?▼

Cross-chain escrow holds funds across multiple blockchains until milestone conditions are met. Agents can fund the escrow, and upon completion, release the payment, or trigger revocation and refund capabilities if required.

Can I use this crypto API to send cross-chain payments on BTC, ETH, and SOL?▼

Yes, this crypto API supports multi-chain transactions across BTC, ETH, SOL, POL, BCH, and USDC. It enables agents to programmatically send cross-chain payments through the integrated REST/SDK interface.

What's the best way to automate escrow release and refunds in automated workflows?▼

The best way to automate escrow operations is by integrating the SDK into your automated workflows. Agents can programmatically manage escrow release upon milestone completion or trigger revocation and refund capabilities.

Do I need a web wallet to create non-custodial wallets for AI agents?▼

No external web wallet is required. The REST/SDK interface directly handles non-custodial wallet creation and management for automated agents, utilizing off-chain signing where applicable to secure transactions.

Are there limitations when managing multi-chain transactions with off-chain signing?▼

Off-chain signing applies where applicable within the multi-chain architecture. Transactions are constrained to the supported networks: BTC, ETH, SOL, POL, BCH, and USDC for escrow and wallet operations.
