Decentralised finance
DeFi
DeFi — decentralised finance — is banking activity that runs on public blockchains instead of inside a bank. Lending, borrowing, saving, exchanging and sending money are written as programs anyone can use, with the terms published in code and the balances verifiable by anyone who cares to look.
What DeFi actually replaces
Lending & borrowing
Deposit an asset into a protocol and earn interest, or borrow against collateral without a credit check, a branch visit or a loan application form.
Stablecoin savings
Hold dollars-pegged tokens such as USDT or USDC and earn a yield on them, instead of leaving idle balances in a non-interest account.
Token swaps & liquidity
Trade one asset for another directly from your own wallet, or supply both sides of a market and earn a share of the trading fees.
Yield & staking
Rewards paid for securing a network or providing liquidity. Rates change constantly and the highest number is rarely the safest one.
Cross-border transfers
Move value to another country on a weekend or a public holiday, with the fee visible before you send rather than after the transfer arrives.
Transparent records
Balances, loans and liquidations are visible on-chain, so anyone can check whether a protocol is actually holding the money it claims to hold.
Why it is relevant here
The friction it removes
- Accounts and transfers that are open every day of the week, not banking hours only.
- Savings and borrowing open to anyone with a wallet, with no credit history required.
- Cross-border payments priced and settled without a correspondent bank in the middle.
- Public records, so a protocol's solvency can be checked rather than trusted.
The risk it puts in your hands
- No bank, no deposit guarantee and no help desk to reverse a mistaken transfer.
- Smart-contract bugs that can drain a protocol overnight, however established it looks.
- Stablecoins that can lose their peg, and yields that can vanish without warning.
- Lost keys or a phished signature mean permanent loss — there is no password reset.
How Silnta approaches DeFi
01
Understand before you fund
If you cannot explain how a protocol makes the money it promises — and what happens when it stops — you should not have funds inside it.
02
Self-custody discipline
Your keys, your assets. That means seed phrases stored offline, separate wallets for testing and nothing kept in a browser extension you use daily.
03
Contract & approval risk
DeFi risk is mostly code risk: revoked allowances, unaudited contracts, oracle failures and governance changes. We teach you to check each one.
04
Exit before entry
Before depositing, confirm you can withdraw on the same day, know the withdrawal fee and know who is left holding the loss if liquidity dries up.
Where we are today
Our DeFi work is education and structured guidance through the Academy and our mentorship programmes. We do not operate a lending platform, we do not take deposits, we do not run liquidity pools and we do not offer yield products of our own. Nothing on this page is an invitation, offer or solicitation to use any regulated product, and we will happily tell you when a protocol you have found is not worth your money.
A word on risk
DeFi protocols can fail completely and permanently, and the person who loses money is the wallet owner. Promised returns are never guaranteed, collateral can be liquidated in a fast move, and a token with no liquidity cannot be sold when you want out. Read our Risk Disclosure, our Terms of Use and our Privacy Policy before committing money to anything.
Start with the basics, not the highest yield
Wallets, networks, gas fees, stablecoins and how a loan is actually collateralised — the Crypto Academy covers all of it before you ever connect a wallet to a protocol.
