Pay anyone on Solana using a phone number or 10-digit TIN instead of a wallet address, with private settlement and SAS-powered identity verification.
Identity Layer
10-digit payment identity for Solana transfers
Verification
Attestation-based identity and trust verification
Fee Model
Network and TSN fees shown before sending
Settlement
Private escrow-backed payment settlement
The world already understands how to pay people through identity. Nigeria uses OPay. India uses UPI. Brazil uses Pix. TrustLink brings that identity-first experience to stablecoin payments on Solana.
Instead of copying complex wallet addresses, users pay a phone number or a permanent Transfer Identity Number (TIN).
Example TIN
4872-1930-41
A 10-digit identifier that protects your wallet address while enabling seamless payments across the TSN network.
Send payments to any phone number registered on TINS. The system resolves the phone to the recipient's TIN and settlement identity.
Your TIN is tied to your identity, not a specific wallet. Change wallets without changing your payment address.
Your actual wallet address stays hidden from recipients. They see only your TIN or verified display name.
TINS maintains a secure mapping between human-readable identifiers (phone numbers, TINs) and settlement identities. When you initiate a payment, TINS resolves the recipient's identifier to their verified settlement wallet without exposing raw addresses.
Each identity on TINS can connect multiple identifiers — phone numbers, social handles, and verification credentials — to a single settlement identity. This creates a portable payment identity that works across applications.
TINS provides identity. SAS (Solana Attestation Service) provides verifiable credentials. Together, they enable trust without exposing personal data.
Verification is optional. Users can receive payments without verification. But when verification is present, it increases confidence for both parties.
SAS
Solana Attestation Service
Verifiable credentials
Zero
Personal Data Exposed
Proof without revelation
Identity verified through trusted SAS issuers
Trusted business and merchant credentials
Human verification without exposing personal data
Verify once and reuse credentials across applications
Connect verified social accounts to your TIN for increased trust. Currently supporting WhatsApp verification with encrypted phone-number linking. X Business verification under integration testing.
Verify once through SAS and reuse your credentials across applications built on TSN. Your attestations persist with your identity, reducing redundant verification while maintaining privacy.
Direct wallet-to-wallet transfers are insufficient for everyday payments. They expose addresses, lack payment intent clarity, and offer no recourse for disputes.
TSN (Transfer Settlement Network) coordinates settlement through escrow-backed flows, crankers, and verifiable off-chain proof trails.
Payment Intent
Sender creates intent with fee transparency
Escrow Hold
Funds secured in protocol-controlled vault
Cranker Execution
Operator executes payout transaction
Settlement Proof
Verifiable off-chain evidence recorded
Funds secured in protocol-controlled accounts
Multi-signature settlement authorization
Verifiable settlement evidence off-chain
Senders don't need SOL for transaction fees. Crankers — network operators — sponsor transaction execution in exchange for a fee included in the transfer amount.

Settlement verification and processing
TSN separates network fees, settlement fees, and infrastructure costs instead of combining everything into a single unclear transaction cost.
TSN SDK provides developer APIs for identity resolution, verification, and payment settlement on Solana. Build applications that consume TINS and TSN without rebuilding payment infrastructure from scratch.
Identity APIs
Resolve TINs and phone numbers to settlement identities
Verification APIs

Settlement APIs
Create payment intents and manage escrow workflows
