P2P Stellar payments · No lending · Optional privacy

P2P Stellar payments with optional privacy.

Zellar is a Stellar-native payment workspace for public peer-to-peer payments, request and receipt organization, settlement evidence, and an optional shielded route planned through STEALTH.

MVP

A P2P payment app users can understand.

Zellar organizes requests, payment reviews, receipts, and settlement evidence without hiding wallet authorization, custody boundaries, or route readiness from the user.

Public P2P

Unstealthed Stellar payments are the first public route: request, review, wallet-controlled signing, submission, and receipt evidence.

PayFi organization

Zellar tracks requests, invoices, receipts, counterparties, and payment status. It does not include loans, credit, yield, underwriting, or custody.

Optional privacy

STEALTH is planned to let a user shield an asset, send shielded value peer to peer, and optionally unshield. The private route remains gated while proof, pool, and recovery work is verified.

STEALTH protocol · optional private P2P route

Shielded peer-to-peer payments inside Zellar.

STEALTH is currently a local review track being prepared for safe Testnet integration. No Zellar shielded transfer is live, audited, or production-ready.

1

Shield asset

Move a reviewed Stellar asset into its matching Soroban pool.

2

Send peer to peer

Create a client-local proof and encrypted output for the recipient.

3

Recover privately

The recipient discovers and restores the shielded output.

4

Unshield optionally

Withdraw to a public Stellar destination when the owner chooses.

Current traction

Pre-Testnet MVP work is underway.

The current build is intentionally safety-gated: no mainnet deployment, real assets, custody, wallet-secret storage, lending, or unreviewed signing has occurred.

Built locally
  • Local Zellar P2P payment review workspace with public and private route states.
  • SEP-7 request generation, Freighter connector, and gated XLM Testnet lifecycle code.
  • PayFi-style request, invoice, receipt, counterparty, and settlement-evidence organization without loans.
  • Fail-closed STEALTH note-vault, recipient-recovery, event-checkpoint, and readiness reviews.
  • Read-only STEALTH source audit and tested STEALTH_DOMAIN_V1 binding for pool, asset, network, and protocol version.

What we are building toward

A usable Zellar P2P payment MVP for Testnet review.

The next product stage moves Zellar from local prototype and architecture work into an accessible Testnet product with public P2P payments, settlement evidence, and a visible optional privacy path.

Integrations used

Stellar, Soroban, Supabase, Freighter, SEP-7, Stellar SDK, Stellar CLI, Passkey Kit pilot, Circom, Groth16, BN254, wasm-bindgen, and browser-local artifact verification.

Safety boundary

Private note material, witnesses, recovery data, and wallet secrets must remain client-local. Servers coordinate app state; they do not custody funds or secrets.

Success criteria

A public MVP where testers can understand Zellar, complete basic public Testnet P2P payment flows, and evaluate an optional STEALTH privacy-payment path.
