The one-line version

You type this in a GitHub issue:

@gitequitybot buy $NVDA 100

A vault gets deployed on-chain under your GitHub ID, 100 USDG gets swapped for gitNVDA through Uniswap V3, and the position sits in your vault until you sell or withdraw. You never opened a wallet. You never paid gas.


Contents


Why this exists

Every developer already has an identity that is stable, public, and hard to fake casually: their GitHub account. GitEquity treats that account as the primary key for a brokerage.

The consequences are practical rather than philosophical:

  • Onboarding is zero steps. If you can comment on an issue, you have an account.
  • Identity is permanent. Vaults bind to the numeric GitHub user ID, which GitHub never reuses and never changes. Rename your handle, keep your money.
  • The interface is the workflow. Bounties, payouts, and treasury moves happen where the work already happens.

How a command becomes a trade

GitHub comment

      v
  Webhook  ──►  Intent parser  ──►  Relayer  ──►  GitEquityVault
                                                        │
                                                  Uniswap V3
                                                        │
                                                  gitNVDA, gitTSLA, ...
  1. issue_comment webhook fires, signature verified against GITHUB_WEBHOOK_SECRET
  2. Command text is parsed into a structured intent: ticker, side, size
  3. Vault is looked up by GitHub user ID, or deployed on first use
  4. Relayer signs a short-lived authorization and submits the transaction, paying gas
  5. Vault routes USDG through Uniswap V3 and holds the resulting stock token
  6. Bot edits its own comment in place with the transaction hash and new balance

Security model

The vault requires two independent signatures for every state-changing call:

Signature Held by Covers
ownerSig Per-user keypair, AES-256-GCM encrypted at rest Vault address, GitHub user ID, nonce, deadline
relayerSig Relayer signing key, hot Issued only after a GitHub command is verified

Neither key alone moves funds. The owner key never pays gas and never appears as msg.sender. Replay is blocked by a monotonic nonce plus a five-minute deadline carried inside every signature.

Swap outputs are constrained to an on-chain whitelist, so a compromised relayer cannot route a swap into an attacker-controlled token.


Contracts

Contract Role
GitEquityVaultFactory Deploys exactly one soul-bound vault per GitHub user ID
GitEquityVault Custody and swap execution, dual-signature gated
GitEquityStockFactory Deploys the ERC-20 receipt token for each ticker
GitEquityStockToken Soul-bound receipt: gitNVDA, gitTSLA, gitAAPL, ...
GitEquityToken Native EQUITY token
GitEquityAirdrop Merkle distributor for EQUITY

Sources and deploy scripts live in gitequity-contracts. Addresses are published to deployments.json after each deploy.


Assets

62 tokenized equities on Robinhood Chain, each verified on-chain through symbol() and decimals(). The registry lives in packages/rwa/src/registry.ts.

A sample of what is tradeable:

Ticker Receipt Ticker Receipt
NVDA gitNVDA TSLA gitTSLA
AAPL gitAAPL MSFT gitMSFT
AMZN gitAMZN GOOGL gitGOOGL
META gitMETA COIN gitCOIN
AMD gitAMD AVGO gitAVGO

Settlement is USDG. Pools are the 1% fee tier for single names, 0.3% for index products.

MCP: trade from your AI client

GitEquity ships an MCP server, so Claude, Cursor, ChatGPT and others can read your portfolio directly.

Reads are direct. Writes always require a confirmation code posted from your GitHub account - the assistant proposes, you approve. An AI client cannot move your money on its own.

Running locally

Requirements: Node 20+, pnpm 9+, PostgreSQL 15+

git clone https://github.com/gitequityorg/gitequity.git
cd gitequity
pnpm install
cp .env.example .env      # fill in the values below
pnpm --filter @workspace/db run migrate
pnpm dev

API comes up on :3000, web on :5173.

To exercise the bot locally, point your GitHub App webhook at a tunnel such as ngrok http 3000, then comment in a repository where the App is installed.


Environment

Variable What it is
GITHUB_APP_ID Numeric ID of your GitHub App
GITHUB_APP_PEM App private key, newlines escaped as \n
GITHUB_CLIENT_ID OAuth client ID
GITHUB_CLIENT_SECRET OAuth client secret
GITHUB_WEBHOOK_SECRET Shared secret for webhook signature checks
SESSION_SECRET Session signing key, 32+ characters
ENCRYPTION_MASTER_KEY 32-byte hex, wraps every stored user private key
DEPLOYER_PRIVATE_KEY Deploys vaults and receipt tokens, pays gas
RELAYER_SIGNING_KEY Signs execution authorizations
DATABASE_URL PostgreSQL connection string

ENCRYPTION_MASTER_KEY cannot be rotated without re-encrypting every stored key. Back it up before going anywhere near production.
