Cross-border medical payments,
settled in seconds.

The problem we settle

Traditional vs SaluBridge

Cross-border medical payments are slow, expensive, and opaque. Stablecoin settlement fixes all three.

Traditional benchmarks: cross-border B2B settlement of 1–5 business days at 3–7% all-in cost in many corridors; global average cost to send $200 cross-border was ~6.4% in Q1 2026. Card rates reflect 2.9% + $0.30 plus ~1.5% international card surcharge and FX spread.

How settlement works

Onboard. Settle. Reconcile.

Three steps. No crypto knowledge required from clinics or patients.

How we're building

Minimal infrastructure. Maximum leverage.

Settlement infrastructure on Crossmint, shipped via factory.ai, pushed to GitHub, orchestrated on Railway.

Under the hood

The SaluBridge Settlement API

Three REST endpoints power the entire settlement flow. Built on the Crossmint Wallets SDK — server-signed, on-chain, explorer-verifiable.

Staging settles in USDXM, Crossmint's USDC-behavior test token. Production settles in USDC on Base. Amounts and addresses shown are illustrative.
