How WithMetis Markets Uses Ceffu to Provide Secure Transaction Routing

2023-07-05  •  3 min read

WithMetis Markets is one of Europe's largest liquidity providers with its fiat on/off-ramp portal, liquidity provision APIs, and for multiple marketplaces, including the Binance peer-to-peer (P2P) marketplace. Acting as a gateway through which individuals and institutional investors can transact with one another for deep liquidity, WithMetis Markets needed a custodian with robust infrastructure to offer its wide range of clients three core solutions: their novel off-exchange settlement, segregated and enterprise-grade cold storage with fast, scalable transaction routing to provide investors with peace of mind that their transactions are managed professionally. Seeing how Ceffu could provide this seamlessly and efficiently, WithMetis Markets engaged us to support its business growth.

Supporting an entire suite of products with speed and scalability

Qualified Wallet is our enterprise-grade, insured cold storage solution that provides institutional clients with segregated, on-chain cold wallets, while our new Co-sign Wallet offers institutional users more speed and control over transaction signatures. By integrating with Ceffu, WithMetis Markets can create segregated wallets for cold storage (which powers its Vault offering) while routing all requested transactions through dedicated on-chain deposit addresses for its off-exchange liquidity provision offering. 

This infrastructure forms the cornerstone of WithMetis Markets' product offering with three main use cases:

  • P2P: it allows the routing of transactions from market makers back to the P2P marketplace

  • Fiat on/off-ramp: when someone receives euros, the transaction gets routed through a Co-sign Wallet to the rightful owner

  • Liquidity provision: businesses can tap directly into deep liquidity by connecting through WithMetis Markets API's. This allows for efficient and direct transaction routing to/from their wallets.

“Our approach to user protection involves collaborating with partners to provide a robust safeguarding and transaction routing framework. In doing so, we pave the way for innovative solutions that facilitate crypto-asset finance while ensuring our users' interests are always safeguarded. The security of Qualified Wallet and Co-sign Wallet, together with the instantaneous transaction capability, perfectly align with our needs. Given our substantial transaction volume, Ceffu's highly competitive fee structure also makes it the optimal choice for our business model.” – George Lamprianidis, CEO – WithMetis Markets

Providing the base layer of institutional protection 

Both our Qualified Wallet and Co-sign Wallet solutions are backed by industry-leading multi-party computation (MPC) technology – the most secure wallet protection system that splits a client’s private key into multiple key shares. Ceffu securely stores those key shares offline on distributed, geographically isolated, air-gapped devices, ensuring the utmost security and protection of our clients' assets. 

With Co-sign Wallet, private keys are split into three key shares, one of which is bound to our clients’ personal device of choice. Transaction approvals require only two out of the three shares – one of which is stored with the user, thereby making the approval process faster and more convenient.

Securing your institutional crypto assets with Ceffu

Ceffu is a compliant, institutional-grade custody platform offering custody and liquidity solutions that are ISO 27001 & 27701 certified and SOC Type 1 & Type 2 attested. Our MPC technology, combined with a customizable multi-approval scheme, provides bespoke solutions allowing our institutional clients to safely store and manage their digital assets.. 

Institutions also benefit from our secure gateway to a wide range of liquidity products within the Binance ecosystem as the Binance Exchange’s institutional custody partner. Mirror, our flagship off-exchange settlement solution, exemplifies this connection by allowing institutional investors to trade on the world’s largest cryptocurrency exchange while their assets remain off-exchange in their Ceffu cold wallet at all times.
