AmericanFortress is an innovative firm developing unique cryptocurrency products that enhance security and convenience. It has developed Send-to-Name, a novel multi-chain system that enables people to send private transactions to wallets using one of AmericanFortress’s human-readable, reusable @Name’s in place of a typical wallet address.
The company is working hard to spread its technology and advance the cryptocurrency industry. Its ecosystem partners include Tron, Dash, Wirex, Arbitrum, and the Litecoin Foundation.
AmericanFortress’s latest development is Zero Knowledge Proofs of Seed Provenance (ZK-POSP), which iterates on zero-knowledge proofs, a technology that enables wallets to prove whether an address was honestly derived from a hidden seed. ZK-POSPs offer cross-chain interoperability and numerous security benefits compared to current systems.
The Advantages of ZK-POSP Over Traditional Systems
AmericanFortress’s ZK-POSP technology has the potential to influence many aspects of the crypto experience due to several unusual characteristics:
- The ability to generate proof that two wallets are controlled by the same owner/hidden secret across multiple blockchains and curves – for example, Bitcoin’s secp256k1 and Solana’s Ed25519.
- Capable of preventing payouts to wallets that are not controlled by the same person, combating money laundering while enhancing compliance for service providers.
- Keeps transactions private. The sender’s name is visible exclusively to the recipient.
- Allows auditors to verify who sent and received transactions without the wallet owner handing over keys, thereby avoiding exposure of their full transaction history.
- While it previously took over 30 minutes to generate one ZK-POSP, AmericanFortress’s innovations have reduced the time to around 6 seconds.
Cryptocurrency bridge platforms are one of the products that can most benefit from leveraging ZK-POSP. Bridge services enable swaps between blockchains, but in doing so, they’ve become an avenue for money laundering. Person A can use a bridge to send assets to Person B indirectly and anonymously, and the platform can do little to mitigate it.
By implementing ZK-POSP, bridge services can easily verify whether two wallets are controlled by the same owner, adding only a few seconds to the overall swap time and ensuring a smooth, efficient user experience, while also enabling platforms to better identify suspicious transactions.
However, benefits are not limited to just compliance. From January to July 2026, bridge services lost around $328 million, primarily due to exploits that trick systems into releasing funds when they shouldn’t. For example, Kelp DAO’s LayerZero-built bridge paid out roughly $292M in rsETH on 19 April due to a forged cross-chain message.
AmericanFortress’s ZK-POSP technology could prevent similar exploits and significantly reduce annual losses for bridge services. It provides another element for the platform to verify. By enabling bridges to verify whether two wallets are derived from the same secret, ZK-POSP can automatically reject transactions from unaffiliated bad actors attempting to bypass security systems or inject malicious code.
Discussing bridges, an AmericanFortress representative said:
“Every bridge today pays whatever address it’s handed. We give it a way to check that the address belongs to the person who made the deposit, without learning anything else about either wallet.”
Looking Forward
Bridge services lose millions annually to exploits that could be prevented by implementing Zero-Knowledge Proofs of Seed Provenance. AmericanFortress has improved verification speed many times over compared to prior iterations, enabling implementation without impacting usability. With bridges regularly processing a high volume of transactions, AmericanFortress could generate significant value in the sector.
Regular people also benefit. Address poisoning is a common scam in which fraudsters send transactions to a wallet using a look-alike address, attempting to trick the recipient into copying the fake transaction’s address and using it in a genuine transaction. ZK-POSP systems enable users to verify whether they own a wallet and identify who sent a transaction, significantly reducing the effectiveness of these attacks.
AmericanFortress’s ZK-POSP has industry-wide ramifications. It can improve security, prevent money laundering, and enhance compliance without adding significant processing time. While its success will be driven by implementation into existing systems, the technology is undeniably interesting.
