Unified Balance is NOT a single shared pool. Each supported chain has its own
GatewayWallet contract (same address 0x0077…19b9, deployed independently).
Depositing on Sepolia stores your USDC in Sepolia's contract; depositing on Fuji stores it in Fuji's. Circle's
REST API then sums all of them into one number = "Unified Balance".
To spend cross-chain: pick a source chain (USDC will be burned from its GatewayWallet) and a
destination chain (USDC minted there). Whole flow takes ~30s with a single EIP-712 signature - no bridge tx, no
wrapped tokens. Tip: deposit on Avalanche Fuji - credits in ~30s vs ~12-15min for
Sepolia / L2 chains (block-finality bottleneck).
How Unified Balance works
// STEP 1
Deposit
Approve USDC and call deposit() on Circle's GatewayWallet. Funds are escrowed and credited to your unified balance immediately.
// STEP 2
Aggregate
Gateway's REST API tracks deposits across every supported chain and returns one aggregated number per token, per address.
// STEP 3
Spend instantly
Sign an EIP-712 burn intent → submit to /v1/transfer → receive an attestation → call gatewayMint on the destination. Done in seconds.
// STEP 4
Withdraw
Need to exit? Initiate a withdrawal on any chain holding your funds; after the protocol delay finalize and the USDC returns to your wallet.

Withdrawals are 2-step: initiate now, then finalize after the delay. We'll show pending withdrawals on this page.
Unified mode spends from multiple chains in one transfer. You'll sign once per source chain (e.g. 3 sigs if 3 chains contribute), then receive ONE attestation that mints the combined amount on the destination - exactly like having a single cross-chain balance.
