MicroEdge works with Coinbase Wallet on Solana
Coinbase Wallet is a fully-supported Solana wallet for MicroEdge. Read-only display, manual-sign execution, and burner-key auto-execution all work.
connecting Coinbase Wallet
MicroEdge supports any Solana wallet that exposes the standard wallet adapter — including Coinbase Wallet. For Phantom-signed manual execution we use the standard window provider; Coinbase Wallet works identically.
read-only vs signing mode
- Read-only: connect Coinbase Wallet, MicroEdge shows your public key + SOL balance. No signing requested.
- Manual sign: click EXECUTE on a signal, backend builds the swap, Coinbase Wallet pops up asking you to approve.
- Auto live: a separate burner wallet (NOT your main Coinbase Wallet) — backend signs server-side using a key you import via the dashboard.
security model
Manual-sign mode: Coinbase Wallet enforces the final approval step. MicroEdge backend never sees your private key — only the public address.
Auto-live mode: backend stores a burner key at backend/secrets/wallet.json with mode 0600 (owner-only). Logger redacts the secret. Recommended for burner wallets funded with $5–10 max, never your main Coinbase Wallet.
faq
Will MicroEdge drain my Coinbase Wallet?
No. Manual mode requires per-transaction approval inside Coinbase Wallet. Auto mode requires you to deliberately import a key — and we recommend a burner.
What if Coinbase Wallet updates and breaks?
MicroEdge uses the Solana wallet standard (wallet adapter spec). Wallet updates usually preserve this interface.
