How to set up a crypto wallet for betting

By Alex Grasbeck8 min readUpdated 26 August 2026

A wallet is either custodial — a company holds the keys and you hold an account with them — or self-custody, where you hold the keys and nobody can move your funds but you. For betting, that distinction decides everything: six of the twelve platforms we rate need you to connect a self-custody wallet, and the other six hold a balance for you instead.

A wallet doesn’t really store coins. It stores the key that proves the coins are yours. Everything that follows — why the seed phrase matters so much, why “lost” usually means permanently — comes from that one fact.

Custodial or self-custody

With a custodial wallet — an exchange account, or a balance on a conventional crypto sportsbook — a company controls the key and credits you on their own ledger. You get password resets and a support desk. You also inherit their solvency, their policies and their decisions about your account.

With self-custody, the key sits on your device. Nobody can freeze your funds, and nobody can restore them for you either. There is no support line, because there is nobody in the middle.

This is not an abstract preference here. Custody carries the heaviest weight in the Degen Score at 30%, because whether a smart contract or a company holds your balance is the difference that survives everything else about a platform.

Which one you need depends on where you bet

Connect a self-custody wallet: SX Bet, Polymarket, Overtime Markets, BetDEX, Bookmaker.xyz, Divvy.bet. There is no deposit and no account balance — you sign a transaction and the bet settles on-chain.

Open an account and deposit: Stake, Cloudbet, BC.Game, DexSport, Vave, Sportbet.one. You can still use a self-custody wallet as the place your bankroll lives between sessions — and you should.

The three kinds of self-custody wallet

Browser extension. The standard way to connect to an on-chain sportsbook. Sits in your browser, pops up to approve each transaction. Most convenient, and the most exposed to what you click.

Mobile app. Same idea on a phone, usually connecting to sites by scanning a code. Good for betting away from a desk.

Hardware wallet. A physical device that keeps the key offline and requires a physical button press to approve anything. Worth it for an amount you would be genuinely upset to lose. Overkill for a small bankroll; sensible for savings that sit behind it.

A common arrangement: a hardware wallet for what you’re holding, and a small browser wallet you actually connect to betting sites, topped up from the first.

Setting one up

Install from the official source. Fake wallet extensions and lookalike download pages are one of the most reliable ways people lose everything. Reach the download through the project’s own domain, not through a search advert.

Write the seed phrase on paper. The wallet shows you a list of words once. That list is your funds — anyone with it has full access from any device, forever. Write it by hand and store it somewhere physical. Not a screenshot, not a photo, not a note in a password manager, not an email to yourself.

The one rule. Nobody legitimate will ever ask for your seed phrase. Not wallet support, not a sportsbook, not an admin in a chat, not us. Every single request you ever receive for it is a theft attempt, without exception.

Match the network to where you’ll bet

A wallet holds assets on specific networks, and a wallet built for one chain generally cannot hold assets on another. Check where your platform actually operates before funding anything: SX Bet settles on its own SX Chain, Overtime Markets runs across Optimism, Arbitrum and Base, BetDEX and Divvy.bet are on Solana, and Polymarket is on Polygon.

Most mainstream wallets handle several networks, but you often have to add a network manually before it appears. Our coin and network guide goes into why this choice also decides what you pay in fees.

Send a small amount first

Before moving a bankroll, move a fraction of it. Confirm it arrives, confirm the wallet displays it, then move the rest. One extra network fee buys certainty on the part of this process that is least forgiving.

Common questions

Do I need a wallet to bet with crypto?

It depends on the platform. Non-custodial books like SX Bet, Overtime Markets, BetDEX and Bookmaker.xyz require you to connect a self-custody wallet - there is no account balance. Custodial books like Stake, Cloudbet and BC.Game only need an account, though keeping your bankroll in your own wallet between sessions is still the safer habit.

What happens if I lose my seed phrase?

With a self-custody wallet, the funds are gone. There is no recovery process and no support desk that can help, because nobody else ever had the key. This is the trade you accept in exchange for nobody being able to freeze or seize your balance.

Is a hardware wallet necessary for betting?

Not for a small bankroll - a browser or mobile wallet is fine for money you are actively betting with. A hardware wallet earns its cost for amounts you would be genuinely upset to lose. A common setup is a hardware wallet for holdings and a small hot wallet for betting.

Can one wallet work on every betting platform?

Only if it supports the right networks. The platforms we rate run on several different chains, and a wallet built for one chain generally cannot hold assets on another. Check which network your platform uses before funding anything.
