Payment Rails (Stablecoin, Fiat On/Off Ramps)
GeSIM uses stablecoins $USDC as the primary settlement currency:
Price stability: avoids crypto volatility risk for carriers.
Fast settlement: transactions confirm on-chain in seconds.
Global reach: works across all jurisdictions where stablecoins are accessible.
Flows:
User Purchases eSIM Plan → user pays in stablecoin (via in-app wallet).
Escrow Contract → funds locked until carrier provisioning receipt is verified.
Carrier Settlement → after verified provisioning, escrow releases funds to carrier wallet.
On/Off-Ramps:
On-ramp: Users can top up their in-app wallet using fiat → stablecoin ie..MoonPay or local PSPs.
Off-ramp: Carriers can withdraw stablecoin balances into fiat bank accounts via regulated exchanges or PSPs.
Batch settlements: for high-volume carriers, payouts can be bundled (e.g., daily or weekly) to minimize fees.
Additional models supported:
Pay-on-Usage: instead of prepaying, users can fund micro-escrows. Funds are released in smaller increments (e.g., per MB consumed).
Hybrid settlement: part prepaid, part pay-per-use for enterprise customers.
