SafeNest, Web3 Treasury SaaS for Teams, DAOs & Agencies

Launch your own white-label Web3 treasury platform in a weekend, not a year.

Overview

SafeNest is a complete, production-ready multi-signature Treasury SaaS built for teams who want to manage shared crypto across Ethereum and Solana without ever touching a single person with the keys.

Unlike basic wallet templates or single-chain multisigs, SafeNest ships as a full business: Stripe-powered subscriptions, team-based access control, role-based governance, an audited dashboard, email automation, and a unified treasury layer that abstracts EVM and Solana into one experience.

Built on Next.js 14, MongoDB, viem, and @solana/web3.js -the codebase is clean, modern, well-typed, battle-tested, API-first, fully documented, and architected for scale.

One Wallet. One Person. One Massive Risk.

Browser wallets like MetaMask and Phantom were designed for individuals - not teams. Your DAO, dev shop, or agency holds shared funds in a single wallet, you've created the worst possible setup.

Single Point of Failure
Single Point of Failure

One phishing link, one stolen seed phrase, one compromised laptop, and the entire treasury is gone. No recovery. No reversal.

No Accountability
No Accountability

Who approved that $50,000 transfer? Was it the CEO? A former employee? A hacker? Browser wallets keep no record of who decided what.

2

No Governance
No Governance

There's no 'wait, let's vote on this.' There's no 'two of us must agree.' Every transaction is final the second one person clicks Confirm.

No Multi-Chain Safety
No Multi-Chain Safety

Managing ETH on MetaMask and SOL on Phantom means switching extensions, juggling networks, and praying you don't paste the wrong address.

No Audit Trail
No Audit Trail

When tax season, an investor diligence call, or a security incident hits, you have a list of transaction hashes. Good luck explaining that to anyone.

Safenest Proposal Lifecycle

The architecture diagram should be the visual centerpiece of the technical credibility section. It must communicate: clean separation of concerns, mature engineering, and easy extensibility.

Creator drafts proposal

Member or contributor - selects wallet, defines calls (transfer, swap, etc.)

Proposal service

Allocates nonce, builds unsigned tx via chain adapter, computes digest, writes PROPOSAL row

Notify members

Email / in-app - contributors get read-only view

Solana - on-chain voting

Each approval costs gas, lands on-chain

EVM - off-chain signatures

Signing is free, only execution costs gas

Member opens Phantom

Signs approve_ix for Proposal account, sends own tx to program

Member opens MetaMask

eth_signTypedData_v4 on digest, posts sig to SafeNest API

Indexer observes event

Updates SIGNATURES table, checks threshold on chain

Backend verifies & stores

ecrecover off-chain, owner check, writes SIGNATURES row

Anyone calls execute

Program CPIs target programs, Vault PDA signs via invoke_signed

Executor submits bundle

Signs sorted asc, packed, sent in single execTransaction call

Indexer confirms tx

Marks PROPOSAL status = executed, stores tx hash for explorer link

Notify all participants

Email + in-app - receipt, audit log entry
