Overview

Vela supports two deposit modes depending on the asset:
  • ETH — fully on-chain via the VelaSettlement smart contract on Ethereum Sepolia. Your funds are locked in the contract, not held by Vela.
  • USDC — fully on-chain via the VelaSettlement smart contract on Ethereum Sepolia. Requires a two-step approve + deposit flow.
  • Other assets (BTC, SOL, AVAX, etc.) — trust-based beta deposits. Funds are credited directly to your engine balance.
