Proxy Chain Routing
Welcome to the Proxy Chains guide. This document explains how the Centiiv Liquidity Protocol enables seamless, automated cross-chain stablecoin routing between external blockchain ecosystems and the core Stellar settlement engine.
What is a Proxy Chain?
A Proxy Chain is an external blockchain (such as an EVM chains) where Centiiv automatically orchestrates cross-chain deposit collection, bridging, and delivery under the hood.
Instead of requiring users or developers to manually interact with external bridges, configure custom RPCs, or wait for standard multi-minute transfer finality, Centiiv handles the entire bridging pipeline natively. Whether depositing assets on a supported proxy chain or receiving funds directly on one, the protocol seamlessly bridges and routes transactions between external networks and our core liquidity contracts.
Supported Directions: Proxy chain routing is supported for both onramps (fiat-to-crypto delivered directly to your destination wallet on a proxy chain) and offramps (crypto-to-fiat from any supported proxy chain).
Supported Networks & Assets
We support cross-chain settlement across major EVM proxy chains with the following token matrix:
| Network | Supported Assets |
|---|---|
| Base | USDC, EURC |
| Arbitrum | USDC, USDT |
| Ethereum | USDC, USDT |
| BSC (Binance Smart Chain) | USDC, USDT |
| Polygon | USDC, USDT |
| HyperEVM | USDC |
Amount Limits: Proxy chain routing supports stablecoin amounts between $0.50 and $10,000 USD per request.
Important: Exact Transfer Amount RequiredWhen offramping on any proxy chain (excluding Base), ensure the amount sent to the provided temporary wallet matches the exact amount specified during request creation.
Any mismatch may cause the transaction to fail and could result in a loss of funds.
How It Works
When you initialize an onramp or offramp request on a proxy chain, the bridging process is fully automated and handled through our institutional partner infrastructure.
1. Request Creation
When calling our request creation endpoint (POST /requests), configure the network parameter to your target proxy chain (e.g. BASE, ARBITRUM, BSC, ETHEREUM, POLYGON, or HYPEREVM).
2. Under-the-Hood Execution
-
Offramp Flow (Crypto-to-Fiat):
Centiiv provisions a temporary deposit address on the source proxy chain. Once your user deposits the specified stablecoin (USDC, USDT, or EURC), our partner infrastructure automatically detects the deposit and bridges it to our Stellar settlement layer for immediate fiat payout. -
Onramp Flow (Fiat-to-Crypto):
Your user pays fiat into a system-generated virtual bank account. Upon payment confirmation, Centiiv triggers instant settlement and uses our partner bridging infrastructure to deliver stablecoin directly to the user's destination wallet on the specified proxy chain.
3. Fast Intent Settlement
Leveraging high-speed intent-based routing through our infrastructure partners, cross-chain transfers finalize in near real-time (~seconds) without requiring native gas tokens (e.g., ETH, BNB, MATIC) from the end-user.
