A Canadian business sends a USDC payment to a supplier overseas. The USDC transfers in seconds. The supplier confirms receipt minutes later.
Behind that transaction, a Layer 1 blockchain processed the transfer — but the Canadian business never saw it, never chose it, and never needed to understand it.
This article explains what Layer 1 blockchains are in the context of business payments — stripped of technical jargon, focused on what matters for payment speed and cost, and written for Canadian business owners and finance teams who want the practical picture, not the engineering white paper.
What Is a Layer 1 Blockchain? (The Highway Analogy)
Think of a Layer 1 blockchain as a highway. The highway itself — the asphalt, the lanes, the signage — is the Layer 1. The cars driving on it — the individual transactions — are the payments.
A Layer 1 blockchain is the base network. It validates transactions, secures the ledger, and maintains the record of who sent what to whom. Everything that happens on that blockchain happens on the Layer 1.
Some blockchains have "Layer 2" networks built on top — like express lanes added to a highway. But for business payment purposes, what matters is the Layer 1 because that is where the transaction is ultimately recorded and settled.
Why Businesses Do Not Need to Choose a Layer 1
If you use a business payment platform to send USDC to a supplier, the platform handles the Layer 1 selection automatically. The platform considers:
-
Which blockchain the supplier can receive USDC on
-
Which chain offers the best combination of speed and cost for this specific transaction
-
Whether the supplier prefers a particular network
The business user sees: "Send USDC to [supplier]." The platform sees: "Route this via Solana — gas fee $0.0002, confirmation in under a second." The user never makes a Layer 1 decision.
But the differences between Layer 1 blockchains matter because they determine the underlying speed and cost of the transaction. Understanding the landscape helps you evaluate whether a payment platform is using efficient infrastructure.
The Main Layer 1 Blockchains for Business Payments
Ethereum
The original smart contract platform. Ethereum is the most established and most decentralized Layer 1 for stablecoin payments. It has processed trillions of dollars in USDC transactions since USDC launched.
-
Strengths: Maximum security and decentralization. The largest ecosystem of wallets, exchanges, and platforms that support it.
-
Weakness for payments: Gas fees can spike during periods of high network activity. A USDC transfer that costs $1 during quiet periods might cost $20 during a network surge.
-
Best for: High-value transactions where security is paramount, or when the recipient only accepts USDC on Ethereum.
Solana
The high-speed, low-cost alternative. Solana is designed for throughput — processing thousands of transactions per second at near-zero cost.
-
Strengths: Sub-second confirmation times. Gas fees measured in fractions of a cent. Ideal for high-frequency or batch payments.
-
Weakness: Less battle-tested than Ethereum. Occasional network outages (though frequency has decreased significantly in 2025–2026).
-
Best for: Regular supplier payments, batch disbursements, and any scenario where speed and low cost are priorities.
Polygon
Ethereum's sidekick. Polygon is a Layer 2 network (technically a sidechain) that runs alongside Ethereum. It offers Ethereum-compatible infrastructure with much lower fees.
-
Strengths: Compatible with the Ethereum ecosystem. Fees are low. Large number of platforms and wallets support it.
-
Weakness: Less decentralized than Ethereum mainnet. Dependent on Ethereum for ultimate security.
-
Best for: Businesses that want Ethereum compatibility without Ethereum gas fees.
Base
Coinbase's network. Base is a Layer 2 built on Ethereum by Coinbase. It is designed primarily for the Coinbase ecosystem.
-
Strengths: Deep integration with Coinbase. Low fees. Growing USDC liquidity.
-
Weakness: Relatively new. Smaller ecosystem than Ethereum or Solana.
-
Best for: Businesses already in the Coinbase ecosystem.

For a Canadian business sending a $10,000 CAD payment to a supplier, the gas fee on any of these networks is negligible compared to the hidden FX markup on a bank wire (2.5% = $250). The Layer 1 choice primarily affects confirmation time and network availability — not the total cost to the business.
What "Gas Fees" Actually Are
A "gas fee" is the transaction fee paid to the blockchain network for processing a transfer. It is not a markup or a hidden cost — it is a visible, network-determined fee.
Gas fees vary by:
-
Network load. When many transactions compete for limited block space, fees rise (especially on Ethereum).
-
Transaction complexity. A simple USDC transfer costs less gas than a complex smart contract interaction.
-
Priority. Users can choose to pay a higher gas fee for faster confirmation, though this is rarely necessary for business payments on modern chains.
For business users, gas fees are typically handled by the payment platform. The platform bundles the gas fee into the displayed transaction cost or absorbs it. The business never needs to calculate or pay gas fees directly.
The Trend: Multi-Chain USDC
USDC is not tied to a single Layer 1. Circle (the issuer of USDC) has deployed USDC natively on Ethereum, Solana, Polygon, Base, Avalanche, and several other blockchains. This is called "multi-chain USDC."
For Canadian businesses, multi-chain USDC means:
-
The payment platform can route through whichever chain the supplier prefers
-
If one chain is congested, the platform can use another
-
The business is not locked into any single blockchain
Most modern payment platforms support USDC on multiple chains and route automatically. The business never needs to specify a chain.
PhotonPay: Multi-Chain Stablecoin Payments for Canadian Businesses
PhotonPay supports USDC transfers on Ethereum (ERC-20) and TRON (TRC-20) — two of the most widely used networks for business payments.
-
Two networks, one simple choice. ou fund in CAD, select the stablecoin and network your recipient uses, and send. Match USDC-ERC20 to an Ethereum wallet. Match USDT-TRC20 to a TRON wallet. That is the only technical decision you need to make.
-
Practical guidance by scenario. Most Canadian importers paying suppliers in North America or Europe will use USDC on Ethereum. Most businesses paying suppliers in Asia, the Middle East, or Africa will find their recipients prefer USDT on TRON — it is faster and cheaper for these corridors, and widely adopted there.
-
Gas fees displayed before you confirm. For most transactions, gas fees are negligible. The platform shows the fee before you confirm the payment, so there are no surprises.
-
Fiat rails alongside blockchain rails. USDC settlement is one payment option among many. The same platform supports SWIFT, SEPA, local clearing, and multi-currency cards. Choose based on the payment need — not the underlying technology.
-
FINTRAC-compliant across all rails. Sanctions screening, transaction monitoring, and compliance checks are applied consistently whether the payment travels on a blockchain or through traditional banking infrastructure.
FAQ
Q: Do I need to know which Layer 1 my payment is using?
No. The payment platform handles chain selection automatically. If your supplier has a preference (e.g., "please send USDC on Solana"), you can specify that — but most suppliers simply provide a USDC address and the platform does the rest.
Q: What happens if a Layer 1 network is congested?
The payment platform monitors network conditions and can route through an alternative chain if the primary chain is congested or experiencing high fees. If no alternative is available (e.g., the supplier only accepts USDC on one chain), the platform may delay the transaction until network conditions improve — though this is rare on modern chains.
Q: Is USDC the same on every Layer 1?
Yes. USDC on Ethereum is the same digital dollar as USDC on Solana or Polygon. The blockchain is the delivery network; the asset is identical.
Q: What if a Layer 1 blockchain fails or shuts down?
Public Layer 1 blockchains are decentralized networks, not single-company services. They cannot be "shut down" by any individual entity. Network outages (where the chain temporarily stops processing transactions) are rare but have occurred. In such cases, multi-chain payment platforms can route through alternative chains.
