Stablecoin and Tokenization Infrastructure for Financial Institutions

TL;DR: There is no single best blockchain for every stablecoin or tokenization product. The practical questions are where dollar-stablecoin liquidity needs to sit, where the institution's controls need to be enforced, and whether the product needs dedicated infrastructure. OP Mainnet gives institutions a public production environment connected to existing liquidity, with no chain to operate. A dedicated OP Enterprise chain adds capacity, configuration, economics, and chain-level controls, run Self Managed or Fully Managed.

• OP Mainnet: a fast path to production, connected to existing dollar-stablecoin liquidity, with no chain to operate.
• Dedicated OP Enterprise chain: dedicated capacity, economics, and chain-level controls, run Self Managed or Fully Managed.
• Compliance depends on how a deployment is built and operated, not on the base chain. The institution issues and controls the assets; the infrastructure is a platform, not an issuer.

Stablecoins and tokenization are in production today. Crypto payment cards alone move more than $750 million a month, and dollar-backed stablecoins settle most of it. For a financial institution the practical question is how to build on it.

What are the deployment options for stablecoin and tokenization products?

There is no single best chain. The practical choice is between two deployment models on the OP Stack: OP Mainnet, a shared public Ethereum Layer 2 connected to existing dollar-stablecoin liquidity with no chain to operate, and a dedicated OP Enterprise chain that adds capacity, configuration, economics, and chain-level controls.

Stablecoin and tokenization decisions are often framed as choosing a chain. In practice the harder questions are the deployment model and where controls sit. A product that needs to reach existing dollar liquidity has different requirements from one that needs dedicated capacity or chain-level transaction controls. Those requirements should decide the setup before a team compares individual platforms.

OP Mainnet is Optimism's public Ethereum Layer 2 network. Its infrastructure and block space are shared, and an application can deploy without taking on chain operations. Because it is Ethereum-aligned, a product deployed there can reach the dollar-stablecoin liquidity and settlement activity that already exist onchain, rather than starting on an isolated network.

A dedicated OP Enterprise chain gives the institution its own capacity, configuration, and economics, plus the ability to implement controls that do not exist at the same layer on a shared network, including sequencer-level sanctions and address screening and permissioned access. The operating model is then Self Managed, where the customer runs the chain infrastructure, or Fully Managed, where the Optimism Foundation deploys, operates, and upgrades it through its subcontractor OP Labs.

What should a financial institution evaluate before choosing infrastructure?

The infrastructure decision is clearer when it is tied to business requirements rather than protocol features. Six questions decide it: where liquidity sits, where controls are enforced, how settlement timing works, who operates the chain, who controls issuance, and how much vendor lock-in the choice creates.

Where does dollar-stablecoin liquidity sit?

Stablecoin volume is concentrated in dollar-backed tokens. As of July 2026, USDC was about 58% and USDT about 26% of crypto card spend, per a16z crypto using Paymentscan data. A product that depends on that liquidity benefits from an Ethereum-aligned public network, where the assets and counterparties already exist.

A dedicated chain becomes more attractive when control over capacity or economics matters more than starting on shared liquidity.

Where are compliance and transaction controls enforced?

No base network makes a financial product compliant by itself. The institution remains responsible for its own regulatory analysis, customer controls, policies, reporting, and approvals. The infrastructure choice determines where those controls can be enforced.

On OP Mainnet, institution-specific controls generally sit at the application level. A dedicated OP Enterprise chain can add sequencer-level sanctions and address screening, integrate providers including TRM, Blockaid, and Forta, and configure permissioned access. None of these capabilities is regulatory approval on its own.

How fast is settlement, and what counts as final?

OP Mainnet confirms transactions in roughly 200 to 250 milliseconds as of publication. That is fast confirmation, not final settlement.

Final settlement comes later, when the transaction reaches finality on Ethereum, which is the point a treasury or risk team uses to decide when funds are economically settled.

Who operates the chain, and what are the service levels?

Dedicated infrastructure creates an operating obligation, and OP Enterprise separates that obligation from the decision to use it. Self Managed keeps chain operations with the customer, with 24/7 incident response and a one-hour SLA for critical issues. Fully Managed moves operations to the Optimism Foundation, with a 99.9% uptime SLA and a 30-minute SEV 1 response.

Who issues and controls tokenized assets?

Tokenization needs a programmable venue, like Ethereum, where issued assets can settle and move, plus institutional controls. The institution retains control of issuance and holds the assets. The infrastructure is a platform, not an issuer: the Optimism Foundation provides the technology, through its subcontractor OP Labs, and operates it under a managed tier.

How much vendor lock-in does OP Stack infrastructure create?

The OP Stack has an MIT-licensed open-source core, which gives a different vendor-risk profile from proprietary chain software. Open source does not make migration costless, since a production system still has integrations, procedures, and counterparties around it. But the underlying software is not locked behind a proprietary license.

What does a stablecoin product on this infrastructure look like in practice?

ether.fi Cash is a current example of the public-network path. It runs on OP Mainnet, with more than 100,000 active cards and more than 300,000 accounts, and a credit backend on a dedicated, ether.fi-operated Aave V4 instance with roughly $30 million in active borrowing. It also offers tokenized assets to its users.

It shows that a financial product, with payments, credit, and tokenization, can reach production on a shared public network.

As market context, crypto card settlement has concentrated on OP Mainnet. As of July 2026, OP Mainnet carried about 29% of crypto card settlement volume, the largest share of any chain, ahead of Solana and Base at roughly 19% each. Finance applications including Aave, Morpho, Uniswap, and Velodrome operate on OP Mainnet.

How does the OP Stack fit stablecoin and tokenization products?

The OP Stack is an MIT-licensed framework for building Ethereum Layer 2 chains. More than 50 production chains use it as of August 2026, and OP Stack chains processed more than 6.8 billion transactions between January and August 2026. For stablecoin and tokenization products, it is useful as a common technical base across both paths.

An institution can start on OP Mainnet when a shared public network connected to dollar liquidity fits their product, then evaluate a dedicated OP Enterprise chain if it later needs more control over capacity, compliance, operations, or economics.

• OP Mainnet: Optimism's public Ethereum Layer 2 network, with shared infrastructure and block space, connected to existing onchain dollar-stablecoin liquidity.
• OP Enterprise: the commercial product for running a dedicated OP Stack chain, with its own capacity, configuration, economics, and chain-level controls, offered Self Managed or Fully Managed.
• Self Managed: an OP Enterprise operating model in which the customer runs the chain infrastructure with support from the Optimism Foundation, including 24/7 incident response and a one-hour critical SLA.
• Fully Managed: an OP Enterprise operating model in which the Optimism Foundation deploys, operates, and upgrades the chain as a managed service through its subcontractor OP Labs, with a 99.9% uptime SLA and a 30-minute SEV 1 response.
• Mission-Critical Support: a Fully Managed support level raising the uptime SLA to 99.95% with a 15-minute SEV 1 response, multi-region deployment, and a dedicated technical account manager.
• Stablecoin: a blockchain token designed to hold a stable value, most often pegged to a fiat currency such as the US dollar. Dollar-backed tokens like USDC and USDT concentrate most stablecoin volume.
• Tokenization: issuing a representation of an asset onchain so it can settle and move programmatically. It needs an Ethereum-connected venue plus institutional controls; the institution retains control of issuance.
• Preconfirmation: a fast, pre-settlement signal that a transaction will be included, roughly 200 to 250 milliseconds on OP Mainnet as of publication. It is not Ethereum finality, which is a separate, later stage.
