Deposit Funds

How to fund your Vela account — ETH and USDC on-chain, or trust-based for other assets

Overview

Vela supports two deposit modes depending on the asset:

Asset	Settlement
ETH	On-chain (VelaSettlement.sol)
USDC	On-chain (VelaSettlement.sol, ERC20)
Other assets	Trust-based (beta)

• 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.

2. Connect your MetaMask wallet
3. Select ETH as the asset
4. Enter the amount and click Deposit
5. MetaMask will prompt you to confirm a transaction to the VelaSettlement contract

Depositing USDC (On-Chain)

USDC deposits are settled on-chain via the VelaSettlement contract. This is a two-step process:

1. Go to vela.monolithsystematic.com/deposit
2. Connect your MetaMask wallet
3. Select USDC as the asset
4. Enter the amount and click Deposit
5. Step 1 — Approve: MetaMask will prompt you to approve the VelaSettlement contract to spend your USDC. Confirm this transaction.
6. Step 2 — Deposit: MetaMask will prompt you to deposit the USDC into the contract. Confirm this transaction.
7. Once both transactions are mined, your USDC is locked on-chain and your engine balance is credited.
