The problem
Dollars move at internet speed. Until they meet a border.
Digital dollars solved half the problem: they move instantly, globally, around the clock. But the moment a payment needs to end in a bank account, the stack fills up: bridges between chains, conversions between tokens, off-ramp vendors per market, and a recipient who wanted currency, not crypto.
Every chain added is another integration: another wallet standard, another bridge to trust, another place where a dollar stops being exactly a dollar for a few minutes. And the last mile is the hardest. Off-ramps vary by market, each with its own onboarding, coverage, and settlement quirks, so the promise of instant global dollars ends in a queue of vendor evaluations.
How it works
Dollars in. Dollars across. Local currency out.
Fund from bank rails or accept stablecoins directly: USDB on Spark, USDC on Solana, Base, and Polygon, USDT on Tron. Every account has its own deposit details, and balances credit the moment funds arrive.
Payments move across supported chains without leaving dollar denomination. The Lightspark API converts between stablecoins automatically; dollars stay dollars whether they ride Spark, Solana, or Ethereum. The conversion is the API’s job, not a step in your flow, so there is no bridge to babysit and no token inventory to manage.
When a payment needs to end in a bank account, Lightspark settles to local rails in 65+ countries. The rate locks at quote; the recipient sees their own currency, not a token. One transaction object follows the payment across every hop, with webhooks at each state change.

Quote, execute, webhook. Every payment reports status through signed webhooks with exponential retry.
Integration
Settlement is two calls. The chains stay underneath.
There is no bridge SDK and no per-chain integration: the quote takes a stablecoin balance on one side and a bank account on the other, and the routing in between is the API’s job. Same two calls whether the dollars ride Spark, Solana, or Ethereum.
