Stablecoins

Stablecoins on Lightning. BTC upside, USD stability.

Bitcoin gives you sovereignty and long-term upside. Stablecoins give you a stable unit of account for rent, payroll and day-to-day spending. Lightning Pay gives you both, in one app, behind one seed phrase.

Why stablecoins live next to Bitcoin

Bitcoin is the savings asset. Stablecoins are the spending asset. Holding both in one non-custodial wallet means you don't have to choose.

BTC for savings

Scarce, decentralised, censorship-resistant. The long-term store of value at the centre of your stack.

Stables for spending

USDC and USDT are pegged to the dollar — predictable enough to price a salary, a mortgage, or this month's rent.

Lightning makes it usable

USDT or USDC on Lightning settles in under a second for a fraction of a cent. No Ethereum gas, no confirmation waits.
What a stablecoin wallet does

Two giants, one self-custody wallet

A stablecoin wallet stores tokens whose price is pegged 1:1 to a currency — almost always the US dollar. The two giants are USDC (issued by Circle, fully regulated in the US, monthly attested reserves of cash and short-term Treasuries) and USDT (issued by Tether, the most liquid stablecoin globally, broader exchange support but a more opaque reserve history).

Lightning Pay supports both, on the Lightning Network, in the same app and behind the same 12-word seed as your Bitcoin. The traditional way to hold a stablecoin was on Ethereum or Tron: $2–20 per transfer, gas-price roulette. On Lightning it costs a fraction of a cent and stays non-custodial throughout.

USDC, USDT — or both?

USDC

The regulated dollar

Default for US-based employers and freelancer clients. Circle is registered as a money transmitter in every US state and publishes monthly reserve attestations. Most "park it and forget it" use cases land here.
USDT

The global liquidity dollar

Ubiquitous for international counterparties and Asia-based exchanges. Larger global liquidity, lower spread when bridging in or out. The default once you leave the US-centric stack.
The choice isn't permanent
Lightning Pay's swap engine converts USDC ↔ USDT in-wallet at 0.1%. Hold the bulk of your spending balance in whichever you prefer; convert on the fly when a counterparty wants the other. The Visa card spends from whichever balance you tag as primary.
Hedging volatility

Lock in dollars without leaving self-custody

Bitcoin's long-term appreciation comes with short-term volatility — 20–40% drawdowns are routine. The old playbook was: send BTC to an exchange, sell to fiat, wire to your bank. Each step adds custodial risk, settlement delay, and a taxable event you may not have wanted.

The stablecoin alternative: when you want to de-risk, swap BTC → USDC or USDT in-wallet at 0.1%. The dollar value of your stack is now stable, the assets are still in your non-custodial wallet, and you can swap back to BTC instantly when you want re-entry. Note: swaps are still taxable disposals in most jurisdictions — the Tax Assistant logs them automatically with cost basis attached.

Remittances that arrive in seconds

Wiring $500 from the US to the Philippines or Mexico through Western Union costs $25–50 and takes 1–3 days. The same transfer in USDT or USDC on Lightning costs a fraction of a cent and settles in seconds, into a non-custodial wallet the recipient controls.

Stablecoin payroll

Freelancers and remote teams: send a Lightning invoice in USDC, get paid in seconds, spend with the Visa card or off-ramp when needed. No SWIFT delays, no intermediary fees, no compliance holds.
