What is DeFi?
Arrow down

DeFi (short for decentralised finance) is an umbrella term for financial applications built on public blockchains, primarily Ethereum. DeFi allows users to take complete control of their assets and interact with other users without intermediation (peer-to-peer), reaching transparent financial agreements that are self-executed independently of any third party by relying on open-source codes.

What is blockchain?
Arrow down

Blockchain is an open and decentralised register containing information such as records of transactions. It exists across many computers that secure the information and make it publicly accessible through the network. Blockchain is the technology that enables the existence of cryptocurrencies such as Bitcoin, Ethereum and MATIC.

What are stablecoins?
Arrow down

Stablecoins are cryptocurrencies where the price is pegged to another asset, such as fiat money (e.g. US Dollars) or exchange-traded commodities (e.g. precious metals). These cryptocurrencies have no volatility because they adopt a stabilisation method such as maintaining a cash reserve as collateral. In this case, the reserve price is correlated to the stablecoin, protecting it from crypto market variations (FIAT-backed stablecoin).

What is tokenisation?
Arrow down

Tokenization is the process of creating digital assets on the Blockchain.

This process can result in the creation of digital financial instruments called tokens. In theory, tokens can be any class of asset (e.g. company shares, derivatives, cryptocurrency, structured product) or a fraction of these. In Switzerland, tokens carry the same rights as real-world assets, acting as a digital store of value but much more flexible and global. Thanks to the blockchain, a token can safely move at the speed of an email, with no intermediation.

The World Economic Forum estimates that the assets digitised in blockchain could represent 10% of the world’s GDP by 2027.

What is a non-custodial wallet?
Arrow down

A blockchain wallet is a software program that holds the unique address of your digital currency.

If you wish to purchase or spend cryptocurrency, you will require a wallet. When you create a blockchain wallet, a private key (seed phrase) will be generated. If a wallet is non-custodial, the user has complete control over their keys, and in turn, their assets, to freely transact in DeFi platforms.

What are smart contracts?
Arrow down

Smart contracts are programmable agreements that can be deployed and run on a blockchain. They automatically execute transactions if the agreed conditions are met without the need for an intermediary. Once a smart contract is deployed, it's not possible to change the given rules.

Learn how Colb works

Colb is powered by four digital products, based on the Ethereum public blockchain as the layer 1 and Polygon Sidechain, as the layer 2.

Ethereum is a widely used, fast, secure, decentralised blockchain. Polygon is a sidechain-based scaling solution for public blockchains like Ethereum, which provides scalability while ensuring a superior user experience in a secured and decentralised manner. In the long-term, we expect to expand our platform through adopting blockchain interoperability technologies, which will integrate our products beyond the Ethereum blockchain.

1. Colb Non-Custodial Wallet

Users have access to our non-custodial wallet, designed to manage digital assets issued by Colb and other Ethereum Virtual Machine (EVM) tokens.

This offers users full control of their assets, and a financial interface with performance impact dashboards of their decentralised investments.

2. Stablecolb (SCB)

Stablecolb (SCB) is our fiat-backed stablecoin, pegged 1:1 to the United States Dollar (USD), which acts as a low-volatility store of value on the blockchain.

The creation (or minting) of our stablecoin must be preceded by a prior deposit of USD fiat currency, which will serve as collateral. The issuance of new stablecoins are created on demand, after a deposit is made by the user.

3. Smart Contracts

Smart contracts are at the heart of Colb’s platform, executing all transactions that take place on the network automatically without any intermediary’s involvement or time loss.

Colb’s smart contracts are built using open source language, frameworks and libraries and run on the ultra-scalable Ethereum sidechain network, Polygon. This means they are able to exist and operate independently of Colb’s front-end, hardware or software.

4. Structured Product Tokens (ctToken)

Our fund-linked structured product tokens will be issued directly on the blockchain. These are a digital financial instrument, recognised by Swiss law, that is born on the blockchain. Each ctToken mirrors the net asset value (NAV) of an exclusive traditional investment fund.

ctToken has the correspondent real-world fund shares deposited in a Swiss bank account, held by a dedicated Trust created by Colb. The Trust funcion is to protect the real-world assets from illegitimate interference and operational risks.
