ZkETHer is where DeFi meets Privacy!
Trade anything anywhere on-chain and make it private with zkETHer.
Atomic swaps
Crosschain transfers
Yield generation
Staking
HODL and much more, Sky is the limit!
zkETHer holds zero custody so user has complete control till end
Zk 🤝 DeFi
Guess I will be moving to the second round of finalist judging for @ETHGlobal Online 2025 tomorrow.
Ztomic-Swap for the win!!!
Let's hope for the best, pretty excited for this one 😄

Currently @zketherProtocol is utilising both zk proofs and FHE in its foundation.
indistinguishability obfuscation though theoretical sounds interesting. This could even improve how blockchains operate at the infrastructure level.
cryptography 101: everyone talks about zk but there’s 2 other things to know:
zk (zero-knowledge) = you can prove something about data without revealing the data itself. eg: “i know the password” without showing the password.
fhe (fully homomorphic encryption) = you can compute directly on encrypted data without decrypting it. so someone can process your private inputs and give you encrypted outputs that you can then decrypt yourself.
io (indistinguishability obfuscation) = much more theoretical (but the ef has given research grants for this), it hides a program’s logic entirely and makes two programs that compute the same function indistinguishable. the “holy grail” of cryptography because it will let you publish code that runs but can’t be reverse-engineered.
tldr:
> zk = prove without revealing
> fhe = compute without revealing
> io = hide the program itself
Circuits are being cooked perfectly 🔪
What are we proving?
Ownership, Intent, hash lock
- Ownership for the note
- Intent to identify the note's currency type (USDC/USDT/zUSDC/zUSDT)
- Zk-SNARK based hash lock for atomic swap settlements
We did it!
