Non-custodial cleanup and account merge.
Step 1 of 6: Connect
Paste the account's public key (starts with G). You'll provide the secret key only at the signing step, right before execution.
Stellar BlackHole is a free, non-custodial web tool that audits a Stellar account and guides you through closing it down — removing trustlines, canceling DEX offers, withdrawing liquidity, selling non-XLM assets, and finally merging the account to reclaim your locked XLM reserves. All transactions are signed in your browser; your secret keys are never sent to any server.
To close a Stellar account you must first remove every sub-entry it holds: cancel open DEX offers, withdraw from liquidity pools, sell or transfer non-XLM balances, delete data entries, and remove trustlines. Once the account holds only native XLM, you run the ACCOUNT_MERGE operation to a destination account. This transfers the remaining balance and reclaims the base reserve. Stellar BlackHole builds this exact ordered plan for you and shows it as a dry-run before you sign.
Yes. Stellar BlackHole is fully non-custodial: signing happens entirely client-side in your browser tab, and secret keys are kept in memory only — never serialized, logged, or transmitted to a server. It also includes a Testnet rehearsal mode, per-step irreversible-action warnings, and a typed confirmation gate before any account merge.
A Stellar account cannot be merged while it still has sub-entries or unmet obligations. The most common blockers are: existing trustlines, open DEX offers, stored data entries, liquidity-pool shares, and unmet multisig thresholds. A hard blocker is sponsoring reserves for other accounts — you must revoke those sponsorships first. Stellar BlackHole audits the account and lists every blocker before you proceed.
An account merge is the Stellar ACCOUNT_MERGE operation, which permanently deletes an account and transfers its entire remaining native XLM balance to a chosen destination account. Merging reclaims the 1 XLM base reserve plus the 0.5 XLM held for each sub-entry, so it is how users recover the XLM that was locked as reserves.
Yes. Stellar BlackHole has a Public/Testnet network toggle. You can fund a Stellar testnet account, add the same trustlines, offers, and data entries, then run the full preview, sign, and execute flow on Testnet to confirm the outcome before performing the irreversible merge on the public network.
Yes. The tool parses the account's signers, weights, and thresholds, computes which keys are required to satisfy the high threshold needed for a merge, and lets you add multiple secret keys until enough signing weight is gathered before submitting each transaction.
Before merging, Stellar BlackHole sells non-XLM classic assets to a base asset using native path payments over Stellar's SDEX and AMM order books, then removes the now-empty trustlines. Soroban token balances and DeFi positions (Blend, Aquarius, Soroswap) are detected and surfaced as a read-only Preview.
