A stablecoin is a promise with software attached. The software is straightforward. Keeping the promise is the hard part, and it is tested precisely when keeping it is most difficult.
The model that holds up
Fiat-backed, one-to-one, with reserves held by a named custodian and attested frequently.
This is unglamorous and it is what has survived. Every design that tried to be cleverer — algorithmic supply adjustment, partial collateral, reflexive backing — has been tested by a market-wide panic and has failed it.
The market has learned this. A new stablecoin without hard backing starts from deep scepticism, and that scepticism is well-earned.
Mint and burn
The core engine, and conceptually simple: fiat arrives, tokens mint; tokens return, fiat goes back and tokens burn.
Where it gets demanding is at the edges:
- Atomicity. Minting must never happen before funds are confirmed, and confirmation is not instant.
- Reconciliation. Circulating supply and reserve balance must match continuously, not monthly.
- Failure handling. A mint that partially completes needs a defined, tested resolution.
- Multi-chain supply. If the token exists on several chains, total supply across all of them must equal reserves, which makes bridging a supply-integrity problem rather than a convenience.
Reserves
Where the money sits, who holds it, and what it is held in.
Cash and short-dated government securities are the only reserve composition that survives scrutiny. Anything reaching for yield is taking duration or credit risk with money that has to be available on demand, and that mismatch is what a redemption run exposes.
The custodian should be named publicly. “A regulated financial institution” is not a disclosure; it is an absence of one.
Proof of reserve
A quarterly PDF is the old standard and it is no longer sufficient.
On-chain proof of reserve publishes attested reserve data continuously through an oracle such as Chainlink, so contracts and users can verify backing directly and in real time.
The engineering is straightforward. The discipline is committing to publish continuously, including on days when the number is inconvenient.
Redemption is the whole product
A stablecoin that cannot be redeemed is a token with a hopeful name.
The peg holds through arbitrage: when the price drifts below par, someone buys and redeems at par for a profit, which pushes it back. That mechanism requires redemption to actually work — promptly, at par, for anyone meeting the terms.
So the redemption path needs to be:
- Public, with the terms and minimums stated plainly.
- Tested under load, not just in a happy-path demo.
- Operationally staffed, because volume arrives in bursts precisely when confidence wobbles.
- Honest about limits, because undisclosed constraints discovered during a panic are what turn a wobble into a break.
Designs that restrict redemption to a small set of approved partners work commercially and concentrate the arbitrage mechanism in very few hands. That is a real trade-off worth being deliberate about.
Treasury operations
Day-to-day, someone is managing reserve composition, banking relationships, mint and burn queues, and the buffer that absorbs timing differences between fiat settlement and token movement.
This is an operational business, not a deployment. Teams that build the contracts and treat the treasury as an afterthought discover the actual workload in month two.
What stays with you
The issuing entity, the banking relationships, the custodian agreements and anything legal are yours and your counsel’s. We build the engine, the reserve accounting, the redemption infrastructure, the proof-of-reserve integration and the operations tooling — and coordinate independent third-party audits before any of it holds real value.
Common questions
How do you build a stablecoin?
A mint and burn engine, a reserve held with a named custodian, a redemption path that works under stress, continuous proof-of-reserve attestation, and the treasury operations to keep the peg. The contract is the simplest part. What decides whether the stablecoin holds is whether redemption actually functions when many people want it at once, which is exactly when it is hardest.
What makes a stablecoin credible?
Reserves anyone can verify and a redemption process that still works on a bad day. The model that holds up is fiat-backed one-to-one, with frequent independent attestation, reserves at a banking partner with a real name attached, and a public redemption path that has been tested under stress rather than described in a document. Credibility comes from verifiability, not from the whitepaper.
What is proof of reserve?
Continuous, verifiable evidence that the assets backing a token actually exist and match the circulating supply. On-chain implementations use an oracle such as Chainlink to publish attested reserve data that contracts and users can check directly. It replaces a periodic PDF with something readable in real time, which is a meaningfully different level of assurance.
Why do stablecoins lose their peg?
Almost always because redemption fails or is believed to be about to fail. If holders are confident they can redeem at par, arbitrage restores the peg automatically. If that confidence goes, no amount of reserve is reassuring because the question becomes whether you can actually get to it. Algorithmic designs without hard backing have repeatedly failed this test.
Does Corum8 build stablecoins?
Yes. We build the mint and burn engine, reserve accounting, redemption infrastructure, proof-of-reserve integration and treasury operations tooling, and coordinate independent third-party audits before mainnet. The issuing entity, the banking relationships and anything legal stay with you and your counsel.
