BUFI Multi-Chain Payments: Send USDC on Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, Unichain, Worldchain, and Solana

BUFI sends USDC payments on Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, Unichain, Worldchain, and Solana with sub-cent fees on L2 networks and native cross-chain transfers via Circle CCTP — no bridge wrappers or wrapped tokens.

The Problem

USDC exists on multiple chains but moving between them is risky: bridges can be hacked, wrapped tokens add counterparty risk, and fees eat into payments. BUFI uses Circle CCTP (Cross-Chain Transfer Protocol) for native, trustless USDC bridging between networks, and lets businesses send payments on whichever chain is cheapest or fastest for each recipient.

Features

Polygon Payments
Send USDC on Polygon PoS with transaction fees around $0.01 and confirmation in ~2 seconds. Ideal for high-frequency, low-value payments (~$0.01 fees, ~2s confirmation)
Base Payments
Send USDC on Base (Coinbase L2) with fees around $0.01 and fast confirmation. Growing ecosystem with strong institutional support (~$0.01 fees, Coinbase ecosystem)
Ethereum Payments
Send USDC on Ethereum mainnet with highest security guarantees. Higher fees (~$1-10 depending on congestion) suitable for large-value transfers (Highest security, variable fees)
Solana Payments
Send USDC on Solana with fees around $0.002 and confirmation in ~400ms. Fastest and cheapest option for time-sensitive payments (~$0.002 fees, ~400ms confirmation)
Circle CCTP Bridging
Move USDC between supported networks using Circle Cross-Chain Transfer Protocol. Native burn-and-mint mechanism — no bridge wrappers, no wrapped tokens, no third-party risk (Native CCTP, no wrapped tokens)
Recipient Network Choice
Each payment recipient specifies their preferred blockchain network. BUFI sends to whatever chain they choose, even if company treasury is on a different network (Per-recipient network selection)
Transaction Verification
Every payment includes on-chain transaction hash with block explorer link for independent verification by both sender and recipient (On-chain verification)
Batch Transfers
Send USDC to multiple recipients on the same network in a single batch transaction to minimize gas costs (Batch payments for gas savings)

Frequently Asked Questions

What is the cheapest way to send USDC for business?

Solana offers the cheapest USDC transfers at ~$0.002 per transaction with ~400ms confirmation. Polygon and Base are also very affordable at ~$0.01. Ethereum mainnet is most expensive ($1-10) but offers highest security. BUFI supports all nine mainnet networks — choose based on cost vs security needs.

How does BUFI handle cross-chain USDC transfers?

BUFI uses Circle CCTP (Cross-Chain Transfer Protocol) for native USDC bridging between Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, Unichain, Worldchain, and Solana. CCTP uses a burn-and-mint mechanism — USDC is burned on the source chain and natively minted on the destination chain. No bridge wrappers or wrapped tokens involved.

Can I send USDC to recipients on different chains?

Yes. Each payment recipient in BUFI specifies their preferred blockchain network. If your treasury is on Polygon but a recipient wants USDC on Solana, BUFI handles the cross-chain transfer automatically via Circle CCTP.

Is Circle CCTP safe for business payments?

Circle CCTP is Circle's official cross-chain protocol for USDC. It uses a native burn-and-mint mechanism backed by Circle (the USDC issuer), eliminating third-party bridge risk and wrapped token counterparty risk. It is the most secure method for moving USDC between supported chains.

How fast are BUFI USDC payments?

Payment speed depends on the network: Solana (~400ms), Polygon (~2 seconds), Base (~2 seconds), Ethereum (~12 seconds). Cross-chain transfers via CCTP add approximately 10-20 minutes for the attestation process.
