🧵 Day 1 of 22 — building DodoRail.
The stablecoin rail for Indian founders selling globally.
Cards + UPI via @dodopayments. USDC on @solana. Bridgeless BTC/ETH via Ika. Agent payments via x402. One merchant dashboard. One settlement currency. Optional privacy. Optional yield.
DodoRail — stablecoin payment rail for Indian SaaS, built for the Solana Frontier hackathon.
USDC settles in seconds. Cards + UPI via @dodopayments. Idle dollars auto-deposit to Kamino for yield.
But there's a stablecoin we underrate: 🧵
Architecturally: jupUSD is just another SPL token. DodoRail absorbs it cleanly.
The interesting bit: holding jupUSD = passive T-bill yield via USDtb backing. That STACKS on top of the Kamino auto-deposit yield we already ship.
Two yield sources, one stablecoin balance.
DodoRail is live now at dodorail.xyz — where all of this stacks today on Solana.
12 sponsor integrations. Solo-built in 22 days. MIT-licensed.
