Multi-chain
PulseChain is the source of truth; Ethereum is a first-class citizen. Native bridge in both directions, one portfolio view, one transaction history.

The friendly
wallet for
PulseChain.
An open-source PulseChain wallet with real transaction simulation, native DeFi tools, and infrastructure we run ourselves. Free for everyone. Pro for the regulars.
Pro gets you 3 addresses for the price of 1, our private RPC, and 60% off swap fees. Free works fine without it.
Support Cappy
Capybaras don't run on snacks alone.
Cappy is "two more weeks" away from launching. I'm using it personally already; it just needs polish, audits, and the unglamorous last-mile work before I'd hand it to strangers.
If you want to help fund Cappy's development and infrastructure, you can send a voluntary contribution. This is not a charitable donation and is not tax-deductible. Contributions do not buy ownership, Pro access, refunds, priority access, revenue share, or any other right or benefit.
Cappy may change, be delayed, or never launch. Crypto sent to this address may be sold or used at our discretion for development, audits, infrastructure, legal, or operating costs. Send only from a wallet you control, not from an exchange. Contributions are final.

"Two more weeks" is a community meme for software that looks ready but isn't quite. Actual timeline: whenever I'm comfortable putting it in other people's hands.
Current infrastructure and development costs are roughly $5K to $7K a month. Closer to 10x that if it becomes PulseChain's default wallet.
Why I made Cappy
I never wanted to
I never wanted to
build a wallet.
Rabby was the wallet I wanted to use. The simulator, the native DeFi tools, the way it got out of your way and let you use the chain. Then they dropped PulseChain support.
People kept using it anyway, half-broken, because nothing else came close. I thought about building a replacement. Honestly, I didn't want to.
I already run RPC nodes and data services for several PulseChain products, so the ops weren't the part that scared me. The moral weight of running a wallet itself was. People trust this kind of software to act consistently every time, and getting that wrong has different consequences than getting most other software wrong.
Then a well-known community member got drained. Using Rabby on PulseChain, in that half-broken state. The simulator was one of the things that stopped working when Rabby left. If it had still been alive that day, the malicious transaction could have flagged before signing. They would have had a chance to see the hack coming and walk away.
I asked the obvious question: why are they still using Rabby? Other wallets objectively work better on PulseChain right now. Then I looked at my own Chrome extensions. Why am I still using Rabby too?
Because it's the wallet I want to use. The wallet I wish worked the way it did before.
Cappy is that fix. I am keeping everything that made Rabby good, and rebuilding the parts PulseChain needs.
What's inside
Stuff Cappy
Stuff Cappy
does for you.
Features I would want a wallet to have. That's the entire filter. If I wouldn't reach for it daily on the chain, it didn't make the list. A couple are still cooking, and those carry an "In the works" tag.
Transaction simulator
Transaction requests run through a dry-run before they leave the wallet. The result is broken down by call tier and tagged by scam class (honeypot, sell tax, mint authority, upgradeable proxy, liquidity rug, blacklist hooks), so you see why a tx is risky, not just that it is.
Native swaps via Piteas
PulseChain's best aggregator routes, wrapped in Cappy's transparent flow. Pro cuts the fee 60% (0.10% vs 0.25%). The fee router and the Piteas call land in a single atomic transaction.
Batch send
Pay up to 256 recipients in one transaction. Paste a CSV, pick fee mode (take from input or from each output), sign once. Pro waives the fee entirely.
Subscribe with anything
$5/month covers three addresses. Pay in PLS, USDC, DAI, or anything that swaps. Cappy routes the conversion via Piteas and lands the subscription in a single tx.
Token analytics
1D / 1W / 1M / 1Y price charts per token, live FDV, and an auto-detector that surfaces new tokens hitting your address. Auto-filter by liquidity floor, source verification, holder count, deployer history, days since launch, and top-holder concentration.
Watch-only offline signing
Export an unsigned tx from a watch-only address, sign it on a cold machine, paste the signed hex back. A standalone broadcast page lives in the wallet for the airgap users among us.
LLM transaction assessment
Plain-English explanation of what a transaction actually does, plus a per-token risk write-up that reads on-chain state and social signals. Designed to catch the subtle approval and signature traps the deterministic simulator can't.
Build attestation
On-chain registry of authentic Cappy releases. The wallet self-attests its own build, and a companion Cappy Attestor extension verifies independently, catching forks and tampered installs before they sign anything.
Two ways

Trust, but verify
We don't ask you
We don't ask you
to take our word for it.
The important trust claims are designed to be checkable. The code is open. The critical infra is ours. Releases will be fingerprinted on chain so mismatched builds can be caught before signing.
Open source
Forked from Rabby's open-source codebase. The wallet, contracts, and this landing page all ship to GitHub when Cappy publicly launches.
Self-hosted infrastructure
Critical chain-data dependencies run on infrastructure we control: archive node, RPCs, and indexers. That keeps the wallet usable even when outside services drop support.
On-chain build attestation
Every Cappy release will be fingerprinted on PulseChain. A companion Cappy Attestor extension verifies your installed wallet against the registry, catching forks and tampered builds.
