You send from your own wallet straight to the exchanger — nothing to connect,
no account, and you stay on this page throughout. Rates are indicative until
a swap is opened.
The swap is carried out by an independent exchanger and the deposit address
above is theirs. holdium.xyz never holds, receives or controls
your funds, has no key to that address, and earns a referral commission.
Opening a swap sends your receiving address, IP, browser and timezone to the
exchanger for their compliance checks; we store none of it. Check their terms,
fees and country restrictions before sending anything.
The only reliable way to avoid a swap site logging your IP and browser is to prevent the site from ever seeing them. That means routing your traffic through a tool that strips or replaces this data before it reaches the exchanger.
You compare privacy policies across swap services by checking what data each service collects, how long they retain it, and whether they share it with third parties. The differences between services are often dramatic, and the phrasing of a policy can hide tracking that a competi
A swap service that will freeze your funds later usually shows its hand before you trade, in the fine print, the flow, or the support desk. The warning signs are concrete and checkable, so treat them as a checklist rather than a vibe.
You can swap crypto directly from a hardware wallet without ever moving funds to a hot wallet or exchange account. The site generates a transaction that sends your hardware-wallet coins to the exchanger, and the exchanger sends the swapped coins back to a receiving address you co
Most token swaps you encounter online begin with a wallet connection request. Connect MetaMask, approve a signature, confirm a transaction. The pattern is so common that many users assume it is the only way. It is not. Holdium.xyz offers a different path: you send funds to an add
A swap site learns only what you choose to give it: a destination address for the asset you want, and a refund address if the swap fails. That is all. It does not learn your identity, your wallet balance, or your transaction history.

How to convert crypto: on-chain vs off-chain
Off-chain (on an exchange)
Your trade happens inside the exchange's own ledger. Nothing
touches the blockchain until you withdraw.
Cheapest and fastest for common pairs
Needs an account and usually ID verification
The exchange holds the coins until you withdraw them
Best for converting to and from cash
On-chain (a DEX or swap)
You swap from your own wallet. The transaction settles on the
chain and you pay its fee.
No account, no custodian — you keep the keys
You pay network fees, which vary a lot by chain
Small or new tokens often only trade here
Slippage and thin liquidity are real costs on low-volume pairs
Before any on-chain swap: check the token's contract address
against a block explorer, start with a small test amount, and review what you
are approving — an unlimited token approval to an unknown contract is how most
wallet drains actually happen.
