Send Mobile Money in Benin and watch it arrive as Lightning sats in seconds. I built the exchange path so a slow provider never swallows your payment.

A freelancer gets a US bank wire and spends it from a bitcoin wallet over Lightning. I built the ACH-in and bank top-up side.

When the bank says one thing and our ledger says another, operators need answers. I wrote the runbooks and reconciliation jobs so a stalled payout is visible and retryable.
Ramper
My own project: pay a Lightning invoice and your family gets M-Pesa or MTN MoMo in Kenya, Tanzania, or Benin. It picks the right rail, shows fees upfront, and tells you what to do when money stalls.
LDK — open source
My merged test upstream: two regtest nodes, a keysend with custom TLV record, asserting payment success — covering spontaneous payments in the Python bindings.
Open source
