how to make a multisig wallet for $0 (free)
multisig wallets are safer than most hardware wallets
> prepare the signers first
- pick 3 to 5 wallets. hardware preferred (different brands)
- each needs its own seed. metal backup
- you only need the public addresses. never the seeds
- 2 - 3 wallets you control
- never 1 of anything. never all-of-n
> deploy on safe (evm)
- go to app.safe.global/
- connect one signer that has gas
- pick the chain (ethereum, base, arb, etc)
- create new safe
- paste the 3 addresses & label them
- set threshold (2 of 3)
- review every character of your address
- deploy, pay gas once, the contract address is your new wallet
> fund and test
- send a tiny amount to the safe address (not any signer)
- propose a tx. get the required signatures. execute
- only then send more money
> solana version (squads)
> go to: app.squads.so/squads
- connect wallet with a bit of sol
- add member public keys
- set threshold
- confirm. vault address is your receiving address
> things you need to know
- safe is the standard. billions locked in it
- you can add/remove owners or change threshold later (needs current threshold)
- start on testnet if you want zero risk practice
> what not to do
- don’t paste a wrong address
- don’t use the same seed on multiple signers
- don’t set threshold to 1 or to the full number of owners
- don’t send big money before a successful test tx
bookmark this. good luck not getting hacked

THE BEST SERVICES FOR CHOOSING A CRYPTO CARD
A short stack of tools I actually use when comparing cards. Each one covers a different angle: hands-on testing, fee tables, real volume, or a full catalog.
1/ @DefiLlama
New dashboard from a team that already ships working DeFi tools.
• ~30 cards, side by side: cashback, FX, annual fee, region, network, issuer
• Tiers expand separately, not one “up to 6%”
• CSV export, next to their card-issuer analytics
Link: defillama.com/crypto-cards
2/ @cryptonoshi
Paulina has personally KYC’d and ordered 100+ cards. Not an aggregator of press releases.
• Benchmarks on fees, limits, cashback, and conversion
• Compare up to 3 cards, plus a country TLDR
• A real “worth it / skip it” ranking from actual use
Link: cryptonoshi.com
3/ @cryptocardsone
47 cards compared on issuer terms, not marketing banners.
• Cashback, staking, ATM, FX, Apple Pay, travel, countries
• Scores are explained, rankings are not sold
• Useful for killing cards that simply do not work in your country
Link: cryptocards.one
4/ @JoinTODEY
Wider catalog than most: hundreds of cards and tiers.
• Filters, compare, tier lists
• Covers cards plus neobanks, QR, and the infra behind them
• Partner offers exist, so still check terms with the issuer
Link: todey.xyz/cards
5/ @Paymentscan
Not “which card to get.” Who is actually processing volume.
• Onchain card and neobank spend, weekly and monthly recaps
• Shows who is growing vs who is only posting “up to”
• Fast filter: a dead product with pretty cashback drops out immediately
Link: paymentscan.xyz
6/ @sweepbaseHQ
140+ card database, not a top-five listicle.
• Fees, cashback, custody, regions, and a spend calculator
• Country guides, including India
• Open dataset: CSV and JSON, updated from issuer terms
Link: sweepbase.net
7/ @BreezeYuan
CardScope, a compact comparison across cashback, staking, ATM, FX, Apple Pay, and country availability.
• Quick side-by-side when you already have a shortlist
• Treat the numbers as a draft and confirm on the issuer site
Link: getcardscope.vercel.app
Always DYOR

好家伙，我们还在研究怎么申请 U 卡， @whop 已经开始教人怎么自己做 U 卡了。
Whop 昨天上线了一个 Neobank 模板，号称 15 分钟就能搭一个自己的“数字银行”。
以前：你充 U → 平台给你发卡 → 你刷卡消费。
现在：别人充 U → 你的平台给他发卡 → 他刷卡 → 你赚手续费。
KYC、账户、充提、转账、Crypto、虚拟 Visa 卡这些底层能力，Whop 基本都给你做好了。你主要负责换自己的品牌、设置费率和拉用户。
更离谱的是，目前官方并没有写需要你自己持有银行或发卡牌照，底层金融合作、发卡、KYC、风控等由 Whop 及其合作方处理；当然平台方和用户最终还是要通过对应的身份/合规审核。
Whop 的U卡目前只是虚拟的（可添加到 Apple Pay/Google Play 以在店内使用 Visa），实体卡制作也即将推出。
