This page is the single source of truth for contract addresses across Velora’s stack. Every other page links here rather than inlining addresses, with one exception: failure-mode rows on API reference pages may cite a specific deployed address inline when the address is the actual diagnostic.
Building integrations that need addresses at runtime? Read /resources/contracts.json — it mirrors the table on this page in machine-readable form, keyed by chainId. Supported chains
Velora supports the following EVM networks. Each chain has Augustus v6.2 (Market routing) deployed; Delta availability is a subset.
- Ethereum (1)
- Optimism (10)
- BNB Chain (56)
- Gnosis (100)
- Unichain (130)
- Polygon (137)
- Base (8453)
- Arbitrum One (42161)
- Avalanche (43114)
The authoritative supported-chain list is queryable at runtime via GET /chains on the Market API. Code should treat this page as a human-readable index and /chains as the runtime source of truth.
Addresses by chain
Each contract is also the ERC-20 spender for its execution mode — approve Augustus v6.2 for Market swaps, the Delta contract for Delta orders (Swap, Limit, TWAP), and AugustusRFQ for OTC/RFQ fills. A — means the contract isn’t deployed on that chain and the corresponding mode is unavailable there. See Token approvals for agents for the spender-by-mode decision rules.
Augustus v6.2 is deployed at 0x6a000f20005980200259b80c5102003040001068 on every supported chain. Delta is deployed at 0x0000000000bbf5c5fd284e657f01bd000933c96d and Delta Wrapped Native (dETH) at 0x0a0d53b6684c7b32b4cbef5fe8483bfcc8406742, both at the same address on every Delta-enabled chain. Fee Claimer is deployed at 0x00700052c0608F670705380a4900e0a8080010CC on every supported chain. AugustusRFQ addresses vary per chain and are listed below.

Contracts
Augustus v6.2
The Market router. All Market POST /transactions/:chainId calldata targets the Augustus v6.2 contract on the requested chain. Deployed at the same address across every supported chain.
Augustus v6.1, v5
Legacy router versions. Still operational but new integrations should target v6.2. Calldata returned by the Market API automatically uses v6.2 unless overridden. Migration: Augustus v5 → v6.2.
Delta contract
On-chain entry point that validates signed Delta orders and executes the winning Portikus fill through settlement. The Delta contract is the spender on EIP-712 typed-data approvals: token approvals for Delta flows must be granted to this address, not to Augustus. Deployed at the same address across every Delta-enabled chain.
Delta Wrapped Native (dETH)
The wrapped-native token Delta uses to represent native ETH (and other native gas tokens) as an ERC-20, at a 1:1 rate. When a user sells native ETH through Delta, their ETH is represented as dETH, which is why a native source needs no ERC-20 approval. Deployed alongside the Delta contract at the same address on every Delta-enabled chain, so native ETH works as a source wherever Delta does. See Native ETH (dETH) for the integration detail.
Portikus settlement
The solver-facing settlement infrastructure. Solvers compete by providing fills through Portikus; the Delta contract reconciles the winning outcome back to the user.
AugustusRFQ
On-chain limit-order and OTC contract. Supports partial fills and bilateral signed orders.
Fee Claimer
Holds partner fees accrued from Market swaps until the partner claims them. Fees taken via partnerAddress accumulate in this contract per chain, and partners withdraw them through the Fee Claimer app. Delta fees never pass through it; they accrue in the Delta contract itself. Deployed at the same address on every supported chain. See Monetization for fee parameters and the claim flow.
