Poseidon lets you delete your encrypted ledger permanently.

Requires your wallet signature to prove ownership. No one else can touch your data.

GDPR compliant. Your keys, your data, your choice.

Submitted Poseidon to CMC, request #1308164

We are thrilled to announce that Poseidon (dApp) is officially approved and searchable directly within @phantom wallet.

True privacy on Solana is no longer hidden, it’s right at your fingertips.

Open Phantom, search "Poseidon," and dive in.

The Poseidon Privacy Wallet Roadmap is finally here.

We are mapping out the future of private finance on Solana. Here is our path to building a comprehensive privacy ecosystem:

Phase 1: Token Support - Deploying support for Token22 and legacy SPL tokens.

Phase 2: OTC Trading Program - Building atomic swaps for peer-to-peer trades and an auction system.

Phase 3: OTC Wallet Program - Launching a new wallet with internal balances and no root expiry limitations.

Phase 4: OTC Wallet dApp - Releasing a frontend for trading and automated liquidity management.

Phase 5: Scale & Optimize - Expanding with batch operations and institutional features.

Dive into the details below. The future is private.

Our buy back and burn protocol has been initiated from the withdrawal fees we have collected.

We keep 1 SOL as a reserve. Anything above that? It’s automatically swapped for $POS and burned forever. No manual steps, no delays. Just pure deflationary mechanics running 24/7.

[Poseidon @poseidoncash]

Poseidon is bringing the next wave of privacy infrastructure, striking the balance between speed and secrecy. The depths have never been so accessible.

Privacy on Solana.

Poseidon is making waves with 0% deposit fees and a low 0.15% withdrawal fee. The future of private DeFi is here, and it's built for scale.

We submitted our entry to the Zypherpunk Hackaton

Poseidon proves that Zcash-level privacy is possible on high-throughput chains like Solana. We built the first zkSNARK shielded pool on Solana, demonstrating that privacy doesn't require sacrificing speed or cost.

We built a zero-knowledge privacy layer for Solana that lets you deposit and withdraw SOL without anyone linking the transactions together.

How it works:

- Deposit funds into a shared pool (goes into the Merkle tree)
- Generate a zkSNARK proof off-chain to prove you own notes without revealing which ones
- Withdraw to any address - the proof verifies everything on-chain without exposing your transaction history

What's unique:

- Groth16 proofs verified directly on Solana (BN254 curve)
- Join-split transactions: combine up to 6 notes, withdraw any amount, keep change as new notes
- Explosive withdrawals: split funds across multiple intermediate wallets for extra privacy
- Two-phase withdrawal system prevents MEV/front-running

Tech stack:

- Rust/Anchor for the on-chain program
- Circom for zkSNARK circuits (Poseidon hash for SNARK-friendly operations)
- TypeScript relayer with WebSocket API
- Sparse Merkle tree with 67M note capacity
- Current state:
- Built and tested on devnet. Full test suite with 53 tests covering security, accounting, and attack vectors. The math checks out, proofs verify on-chain, and withdrawals are unlinkable.

What we learned:

*Fitting zkSNARK verification into Solana's compute limits required creative optimizations. The compressed memo format and two-phase withdrawal design came from hitting transaction size constraints hard.*

Deposit and Withdrawal on Poseidon takes a few seconds to complete. (Explosive Withdrawal will take longer depending on how many hops).

2016: $ZEC pioneered zkSNARK privacy, proving the math worked.

2019: Tornado Cash $TORN proved that DeFi users desperately wanted privacy for transactions.

2020: $SOL introduced high-throughput, low-latency DeFi.

2025: Poseidon combines all three. It takes the "gold standard" cryptography of Zcash and deploys it at the speed of Solana.

Poseidon explosive withdrawals have been live for 48 hours.

Your withdrawal splits across 10 intermediate wallets. Each hop creates separation between deposit and destination.

One hop mode: your withdrawal fragments into 10 random amounts (5-20% each).

Each intermediate wallet forwards to your final address. No direct on-chain link between deposit and withdrawal.

Deterministic splits use your transaction nonce as seed. Looks random to chain observers.

Reproducible for verification. Same Groth16 zkSNARK proofs as standard withdrawals.

The program handles split logic. Relayer coordinates forwards.

Privacy through graph breaking, not obfuscation. Clean cryptographic separation.

Multi-hop takes it further: each of those 10 wallets splits again.

Multiple merge points. Exponential graph complexity. Each layer adds another separation degree.

All intermediate wallet keys returned to you, encrypted with your master key.

Non-custodial design. You own the keys. You control recovery.

Parallel processing handles production load. Batches of 4 concurrent merges.

Built for mainnet volume, not testnet experiments.

Final sweep after each hop checks for stuck funds.

Emergency drain clears any remaining dust. Zero tolerance for leftover balances. Everything merges to your address.

History tab provides full verification. Decrypt intermediate keys, check balances, recover stuck funds with one click.

Complete transparency on withdrawal routing.

All proofs verified client-side in your browser.

Decrypt memos, validate amounts, check wallet states. Zero trust in relayer infrastructure.

This is how private transfers work on Poseidon.

Chain analysis sees fragmented hops. You see the full path with cryptographic verification.

If you must ask for privacy, you don't have it. You must have the tools to take it.
